        The Light Dark Matter eXperiment (LDMX)

        The constituents of dark matter are still unknown, and the viable possibilities span a very large mass range. Specific scenarios for the origin of dark matter sharpen the focus on a narrower range of masses:  the natural scenario where dark matter originates from thermal contact with familiar matter in the early Universe requires the DM mass to lie within about an MeV to 100 TeV. Considerable experimental attention has been given to exploring Weakly Interacting Massive Particles in the upper end of this range (few GeV – ~TeV), while the region ~MeV to ~GeV is largely unexplored. Most of the stable constituents of known matter have masses in this lower range, tantalizing hints for physics beyond the Standard Model have been found here, and a thermal origin for dark matter works in a simple and predictive manner in this mass range as well. It is therefore an exploration priority. If there is an interaction between light DM and ordinary matter, as there must be in the case of a thermal origin, then there necessarily is a production mechanism in accelerator-based experiments. The most sensitive way (if the interaction is not electron-phobic) to search for this production is to use a primary-electron beam to produce DM in fixed-target collisions. The Light Dark Matter eXperiment (LDMX) is a planned electron-beam fixed-target missing-momentum experiment that has unique sensitivity to light DM in the sub-GeV range. This contribution will give an overview of the theoretical motivation, the main experimental challenges and how they are addressed, as well as projected sensitivities in comparison to other experiments.

        Exploring the Electromagnetically Interacting Dark Matter at the International Linear Collider

        Dark Matter being electrically neutral does not participate in electromagnetic interactions at leading order. However, we discuss here fermionic dark matter (DM) with permanent magnetic and electric dipole moment that interacts electromagnetically with photons at loop-level through a dimension-5 operator. We discuss the search prospect of the dark matter at the proposed International Linear Collider (ILC) and constrain the parameter space in the plane of the DM mass and the cutoff scale $\Lambda$. At the 500 GeV ILC with $4$ ab$^{-1}$ of integrated luminosity we probed the mono-photon channel and utilizing the advantages of beam polarization we obtained an upper bound on the cutoff scale that reaches up to $\Lambda = 3.72$ TeV.

        Higgs self-coupling at the FCC-hh

        The measurement of the Higgs self-coupling will be one of the benchmarks at a future hadron collider at 100 TeV, like the FCC-hh. Here we present an analysis based on the envisioned integrated luminosity of 30 ab$^{-1}$, using fast simulation samples with different systematics scenarios. The studies combine the decay channels in bb$\gamma \gamma$ and bbll+MET, to achieve a precision on $k_\lambda$ around 3 to 5 $\%$, depending on the scenario.

        The progress of Super Tau Charm Facility in China

        The proposed STCF is a symmetric electron-positron beam collider designed to provide e+e− interactions at a centerof-mass energy from 2.0 to 7.0 GeV. The peaking luminosity is expected to be 0.5×10^35 cm−2s−1. STCF is expected to deliver more than 1 ab−1 of integrated luminosity per year. The huge samples could be used to make precision measurements of the properties of XYZ particles; search for new sources of CP violation in the strange-hyperon and tau−lepton sectors; make precise independent mea-surements of the Cabibbo angle (theta)c) to test the unitarity of the CKM matrix; search for anomalous decays with sensitivities extending down to the level of SM-model expectations and so on. In this talk, the physics interests will be introduced as well as the the recent progress on the project R&D.

        The LHeC and FCC-eh experimental program

        Leveraging the novel concept of Energy Recovery Linacs (ERL), we present the LHeC and FCC-eh colliders that allow the exploration of electron-hadron interactions above the TeV scale. The presented design of the electron accelerator is based on two superconducting linear accelerators in a racetrack configuration that can produce lepton beam energies in excess of 50 GeV. In energy recovery mode, where the beam energy of the colliding beam is recovered for the acceleration of the next beams of particles, the accelerator is capable of reaching luminosities in excess of $10^34$ cm$^{-2}$s$^{-1}$ with an energy footprint of around 100 MW for the electron accelerator. The proposed collider concept enables luminosity values high enough for a general-purpose experimental program. While the envisaged physics results have the potential to empower the HL-LHC or FCC-hh physics results, they also include flagship EW, Higgs, QCD and top quark measurements beyond current precision,and complementary searches Beyond Standard Model. New thematic ep/eA@CERN working groups are established and synergistic efforts are pursued with the HL-LHC and the EIC programs.

        Physics Potential, Accelerator Options, and Experimental Challenges of a TeV-Scale Muon-Ion Collider

        A TeV muon-ion collider could be established if a high energy muon beam that is appropriately cooled and accelerated to the TeV scale is brought into collision with a high energy hadron beam at facilities such as Brookhaven National Lab, Fermilab, or CERN. Such a collider opens up a new regime for deep inelastic scattering studies at unprecedented small Bjorken-$x$ and high $Q^{2}$, as well as facilitating precision QCD and electroweak measurements and searches for beyond Standard Model physics. We revisit the potential physics program of a muon-ion collider and summarize some accelerator design options. New studies on unique key physics observables in $\mu$-p and $\mu$-nucleus will be presented. The associated experimental challenges from beam-induced backgrounds on physics signals are also explored. Initial studies of a forward muon spectrometer design applicable for a muon-ion or muon-muon collider experiment will be presented.

        A detector for future DIS at the energy frontier

        The proposed Large Hadron-electron Collider and the Future Circular Collider in electron-hadron mode will make possible the study of DIS in the TeV regime. These facilities will provide electron-proton (nucleus) collisions with per nucleon instantaneous luminosities around $10^{34}$($10^{33}$) cm$^{−2}$s$^{−1}$ by colliding a 50-60 GeV electron beam from a highly innovative energy-recovery linac system with the LHC/FCC hadron beams, concurrently with other experiments for hadron-hadron collisions. The detector design was updated in the 2020 Conceptual Design Report. Ongoing developments since then include an improved interaction region design, reflecting state-of-the-art synchrotron radiation simulations, together with a more detailed study of an all-silicon central tracking detector. Additional capabilities for particle identification, enabling improved semi-inclusive DIS and eA studies, are also under study. In this talk, we describe the current detector design and ongoing discussion in the framework of a new ep/eA study being carried out on behalf of CERN, highlighting areas of common interest with other future collider experiments and the new Detector R&D Collaborations in Europe.

        Overview of ALICE Upgrades

        ALICE 3 is proposed as the next-generation experiment to address unresolved questions about the quark-gluon plasma by precise measurements of heavy-flavour probes as well as electromagnetic radiation in heavy-ion collisions in LHC Runs 5 and 6. In order to achieve the best possible pointing resolution a concept for the installation of a high-resolution vertex tracker in the beam pipe is being developed. It is surrounded by a tracker based on monolithic active CMOS pixel sensors covering roughly 8 units of pseudorapidity. To achieve the required particle identification performance, a combination of a time-of-flight system and a Ring-Imaging Cherenkov detector is foreseen. Further detectors, such as an electromagnetic calorimeter, a muon identifier, and a dedicated forward detector for ultra-soft photons, are being studied. In this presentation, we will explain the detector concept and its physics reach as well as discuss the R&D challenges.

        Future Physics with CMS detector at HL-LHC

        The High-Luminosity Large Hadron Collider (HL-LHC) is expected to deliver an integrated luminosity of up to 3000 fb-1. The very high instantaneous luminosity will lead to about 200 proton-proton collisions per bunch crossing (“pileup”) superimposed on each event of interest, providing extremely challenging experimental conditions. Prospects for Standard Model (SM) measurements and searches beyond the SM are discussed.

        ATLAS ITk Pixel Detector Overview

        In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The innermost part of the ITk will consist of a pixel detector, with an active area of about 13 m^2. To deal with the changing requirements in terms of radiation hardness, power dissipation and production yield, several silicon sensor technologies equipped with novel ASICs connecting by bump-bonding technique will be employed in the five barrel and endcap layers. As a timeline, it is facing to pre-production of components, sensor, building modules, mechanical structures and services.
        This contribution presents the status of the ITk-pixel project focusing on the lessons learned and the biggest challenges towards production, from mechanics structures to sensors, and it will summarize the latest results on closest-to-real demonstrators built using module, electric and cooling services prototypes.

        Upgraded Lucid and Zero Degree Calorimeter Detectors for ATLAS at the High Luminosity LHC

        The ATLAS pp physics program at the High Luminosity LHC (HL-LHC) requires precision luminosity measurement with systematic control better than 1% during operation with up to 200 simultaneous interactions per crossing. ATLAS will feature several luminosity detectors but at least one of them must be both calibratable in the van der Meer scans at low luminosity and able to maintain accuracy at the highest luminosities. LUCID-3, the upgrade of the present ATLAS luminometer (LUCID-2), will fulfill these requirements.

        The LHC heavy ion community has mapped out a large range of physics measurements at the HL-LHC that will push forward our understanding of both QCD, QED and even electroweak physics that requires zero-degree calorimeters for both triggering and offline event classification. The modified geometry of the HL-LHC requires new detectors that are both thinner and much more radiation hard. A joint project between ATLAS and CMS is underway to construct calorimeters for the HL-LHC that would be used by both experiments.

        This talk will present the designs for the LUCID-3 and HL-LHC ZDC detectors and discuss specific aspects of the HL-LHC geometry and radiation environment that affect the design of the detectors. For LUCID-3, two options are being studied: the first is based on photomultipliers (PMT) as for LUCID-2, while the second is based on optical fibers. Both solutions aim at reducing the acceptance of the detector to avoid the saturation of the luminosity algorithms. Results obtained from prototype detector installed in ATLAS in Run-3 are discussed. ZDCs at the LHC are typically tungsten-sampling calorimeters using quartz Cherenkov radiators. The upgraded ZDCs will use very radiation hard fused silica rods that resulted from an R&D program involving the ZDC teams, the LHC BRAN group, and private companies. The resulting design of the calorimeters and expectations for their performance will be discussed.

        Upgrade of ATLAS Hadronic Tile Calorimeter for the High Luminosity LHC

        The Tile Calorimeter (TileCal) is the hadronic calorimeter covering the central region of the ATLAS experiment. The High-Luminosity phase of LHC, delivering five times the LHC nominal instantaneous luminosity, is expected to start in 2029. TileCal will require new electronics to meet the requirements of a 1 MHz trigger, higher ambient radiation, and to ensure better performance under high pile-up conditions. Both the on- and off-detector TileCal electronics will be replaced during the shutdown of 2026-2028. Approximately 10%of the PMTs, those reading out the most exposed cells, will be replaced. PMT signals from every TileCal cell will be digitized and sent directly to the back-end electronics, where the signals are reconstructed, stored, and sent to the first level of trigger at a rate of 40MHz. This will provide better precision of the calorimeter signals used by the trigger system and will allow the development of more complex trigger algorithms. The modular front-end electronics feature radiation-tolerant components and redundant design to minimize single points of failure. The timing, control and communication interface with the off detector electronics is implemented with modern Field Programmable Gate Arrays (FPGAs) and high speed fibre optic links running up to 9.6 Gb/s. The TileCal upgrade program has included extensive R&D and test beam studies. A Demonstrator module equipped with the new electronics but with reverse compatibility with the existing readout system was inserted in ATLAS in August 2019 for testing in actual detector conditions. The status of the various components and the results of test-beam campaigns with the electronics prototypes will be discussed.

        Machine Learning for Real-Time Processing of ATLAS Liquid Argon Calorimeter Signals with FPGAs

        The Phase-II Upgrade of the LHC will increase its instantaneous
        luminosity by a factor of 7 leading to the HL-LHC era.
        At the HL-LHC, the number of proton-proton collisions in one bunch
        crossing, pileup, increases significantly, putting stringent
        requirements on the LHC detectors electronics and real-time data
        processing capabilities.

        The ATLAS LAr calorimeter measures the energy of particles produced
        in LHC collisions. It also feeds the ATLAS trigger to identify
        interesting events. To enhance the ATLAS physics discovery potential
        at HL-LHC, an excellent energy resolution and an accurate time
        detection is crucial.

        The computation of the deposited energy is performed using
        electronic boards based on FPGAs. Currently this computation is done
        using optimal filtering algorithms that are adapted to situations with
        limited pileup.
        With the increased luminosity and pileup,
        the performance of the optimal filter algorithms decreases.

        The off-detector electronic boards for the LAr Phase-II Upgrade
        will use the next generation of INTEL FPGAs with increased processing
        power and memory.
        This will allow the use on these boards of more complex algorithms.
        We developed several neural networks (NNs) with
        significant performance improvements with respect to the optimal
        filtering algorithms.

        Five NN algorithms will be presented. The improvement of the energy
        resolution and the accuracy of the deposited time compared to the legacy
        filter algorithms will be discussed.
        The implementation of these networks in firmware will be shown.

        Expected performance of the ATLAS ITk detector for HL-LHC

        The increased instantaneous luminosity levels expected to be delivered by the High-Luminosity LHC (HL-LHC) will present new challenges to High-Energy Physics experiments, both in terms of detector technologies and software capabilities. The current ATLAS inner detector will be unable to cope with an average number of 200 simultaneous proton-proton interactions resulting from HL-LHC collisions. As such, the ATLAS collaboration is carrying out an upgrade campaign, known as Phase-II upgrade, that foresees the installation of a new all-silicon tracking detector, the Inner Tracker (ITk), designed for the expected occupancy and fluence of charged particles. The new detector will provide a wider pseudorapidity coverage and an increased granularity. In this contribution the expected performance of the ITk detector will be presented, with emphasis on the improvements on track reconstruction resulting from the new detector design.

        ALICE Forward Calorimeter upgrade (FoCal): Physics program and performance

        The FoCal is a high-granularity forward calorimeter to be installed as an ALICE upgrade subsystem during the LHC Long Shutdown 3 and take data during the LHC Run 4. It will cover a pseudorapidity interval of $3.4 < \eta < 5.8$, allowing to explore QCD at unprecedented low Bjorken-$x$ of down to $\approx 10^{-6}$ -- a regime where non-linear QCD dynamics are expected to be sizable. It consists of a compact silicon-tungsten sampling electromagnetic calorimeter (FoCal-E) with pad and pixel longitudinal and transverse segmented readout layers to achieve high spatial resolution for discriminating between isolated photons and decay photon pairs. Its hadronic component (FoCal-H) is constructed from copper capillary tubes filled with scintillator fibers and used for isolation energy measurement and jets.

        The FoCal detector extends the ALICE physics program with the capability, unique at the LHC, to investigate gluon Parton Distribution Functions (PDFs) in the low-$x$ regime. This not only enables the study of non-linear QCD effects such as gluon saturation, but also allows to provide experimental constrains for (nuclear) PDFs in a region of phasespace where experimental data is scarce. The detector design allows carrying out these explorations using a multitude of probes, including direct photons, jets, as well as photo-production of vector mesons such as the J/$\psi$ in proton-Pb and Pb-Pb ultra-peripheral collisions. In addition, correlations of different probes can be studied, including gamma-jet, jet--jet and $\pi^0$--$\pi^{0}$ correlations.

        In this presentation, we give an overview of the small-x physics program of the FoCal detector, as well as an overview of the expected performance of the detector for various observables. The latter is quantified using recent experimental results of ever-improving prototypes of the detector, which were operated at the Test Beam facilities of CERN in the years 2021--2023. Furthermore, simulation studies are presented, which showcase the robustness of the detector design and its physics potential.

        The LHCb Upgrade II

        The Upgrade II of the LHCb experiment is proposed for the long shutdown 4 of the LHC. The upgraded detector will operate at a maximum luminosity of 1.5×1034 cm-2 s-1, with the aim of reaching a total integrated luminosity of ∼300 fb-1 over the lifetime of the HL-LHC. The collected data will allow the full exploitation of the flavour physics capabilities of the HL-LHC, probing a wide range of physics observables with unprecedented accuracy. Among these, unique sensitivities are expected for the measurement of CKM phases and charm CP violation, as well as in rare heavy-quark decays.
        To achieve this ambitious programme, the current detector performance must be maintained at the expected maximum pile-up of ∼40, and even improved in certain specific areas. To meet this challenge, it is planned to replace all existing spectrometer components to increase the granularity, reduce the amount of material in the detector and exploit the use of new technologies, including precision timing on the order of tens of picoseconds. Following the approval of a framework TDR and physics case document, detailed discussions on detector scenarios, institutional participation and funding are now underway, with the aim of starting the subdetector TDR phase immediately after.
        The presentation will review the key points of the physics programme and the main options of the detector design.

        The Phase-2 upgrade of the CMS Beam Radiation, Instrumentation and Luminosity system

        To fulfill the requirements of the high-luminosity upgrade of the LHC (HL-LHC) CMS is upgrading its Beam Radiation, Instrumentation and Luminosity (BRIL) system which provides real-time and high-precision luminosity determination, beam-timing, beam-loss, beam-induced background (BIB) and neutron and mixed-field radiation environment monitoring. The recent status of this diverse project will be reported, with an emphasis on luminometry that includes the construction of a dedicated detector, the fast beam conditions monitor (FBCM) with Si-pad sensors and a fast triggerless readout, which will operate independently from the central CMS TCDS and DAQ services. Various CMS subsystems' readout will be adapted to provide luminosity information as well. Notably the tracker endcap pixel detector (TEPX) will feature a dedicated readout system for luminosity and BIB monitoring in real time. The independent operation of FBCM and the innermost layer of TEPX from the rest of CMS will be enabled by a dedicated timing and trigger infrastructure. A novel neutron spectrometer has also been recently introduced to the BRIL upgrade project.

        Technical challenges and performance of the new ATLAS LAr Calorimeter Trigger

        To cope with the increase of the LHC instantaneous luminosity, new trigger readout electronics were installed on the ATLAS Liquid Argon Calorimeters.

        On the detector, 124 new electronic boards digitise at high speed 10 times more signals than the legacy system. Downstream, large FPGAs are processing up to 20 Tbps of data to compute the deposited energies. Moreover, a new control and monitoring infrastructure has been developed.

        This contribution will present the challenges of the commissioning, the first steps in operation, and the milestones still to be completed towards the full operation of both the legacy and the new trigger readout paths for the LHC Run-3.

        Development of the ATLAS Liquid Argon Calorimeter Readout Electronics for the HL-LHC

        A new proton-proton collisions era at 14 TeV will start around 2029 with the
        HL-LHC. To withstand the higher radiation doses and the harsher data taking
        expected at HL-LHC, the ATLAS Liquid Argon (LAr) Calorimeter readout
        electronics needed an upgrade.

        The LAr electronic upgrade is composed of four main components.

        1: New front-end boards which will allow to amplify, shape and digitise
        the calorimeter’s ionisation signal on two gains over a dynamic range
        of 16 bits and 11-bit precision.
        Custom preamplifiers and shapers were developed using CMOS
        technologies.
        Two concurrent preamp-shaper ASICs were designed. “ALFE” was selected
        to be the best. Results of the latest version of this ASIC is
        presented.
        ALso, results on a new developed ADC chip called “COLUTA”, the production and
        the ongoing integration tests are shown.

        2: New calibration boards which will allow the precise calibration of all
        182468 channels of the calorimeter over a 16-bit dynamic range.
        A non-linearity of one per mille and non-uniformity of
        0.25% shall be achieved.
        The latest versions of the 2 ASICs that passed recent PDR are presented.

        3: New ATCA-compliant signal processing boards (“LASP”) which will receive
        the detector data at 40 MHz where FPGAs connected through lpGBT
        links will perform energy and time reconstruction.
        The latest development status of the board and the firmware
        are shown. For the first time machine-learning techniques
        are considered for these FPGAs.

        4: A new timing and control system, “LATS”, will synchronise with
        the aforementioned components. Its current design status is shown.

        The ATLAS ITk Strip Detector System for the Phase-II LHC Upgrade

        ATLAS is currently preparing for the HL-LHC upgrade, with an all-silicon Inner Tracker (ITk) that will replace the current Inner Detector. The ITk will feature a pixel detector surrounded by a strip detector, with the strip system consisting of 4 barrel layers and 6 endcap disks. After completion of final design reviews in key areas, such as Sensors, Modules, Front-End electronics and ASICs, a large scale prototyping program has been completed in all areas successfully. We present an overview of the Strip System, and highlight the final design choices of sensors, module designs and ASICs. We will summarize results achieved during prototyping and the current status of production and pre- production on various detector components, with an emphasis on QA and QC procedures.

        ATLAS upgrades for High Luminosity LHC

        While the on-going Run-3 data-taking campaign will provide twice the integrated proton-proton luminosity currently available at the LHC, most of the data expected for the full LHC physics program will only be delivered during the HL-LHC phase. For this, the LHC will undergo an ambitious upgrade program to be able to deliver an instantaneous luminosity of $7.5\times 10^{34}$ cm$^{-2}$ s$^{-1}$, allowing the collection of more than 3 ab$^{-1}$ of data at $\sqrt{s}=$13.6 (14) TeV. This unprecedented data sample will allow ATLAS to perform several precision measurements to constrain the Standard Model Theory (SM) in yet unexplored phase-spaces, in particular in the Higgs sector, a phase-space only accessible at the LHC. To benefit from such a rich data-sample it is fundamental to upgrade the detector to cope with the challenging experimental conditions that include huge levels of radiation and pile-up events. The ATLAS upgrade comprises a completely new all-silicon tracker with extended rapidity coverage that will replace the current inner tracker detector; a redesigned trigger and data acquisition system for the calorimeters and muon systems allowing the implementation
        of a free-running readout system. Finally, a new subsystem called High Granularity Timing Detector will aid the track-vertex association in the forward region by incorporating timing information into the reconstructed tracks. An important ingredient, relevant to almost all measurements, is a precise determination of the delivered luminosity with systematic uncertainties below the percent level. This challenging task will be achieved by collecting the information from several detector systems using different and complementary techniques.
        This presentation will describe the ongoing ATLAS detector upgrade status and the main results obtained with the prototypes, giving a synthetic, yet global, view of the whole upgrade project.

        Overview of the ePIC Detector

        The Electron-Proton/Ion Collider Experiment (ePIC) Collaboration was formed to design, build, and operate the Electron-Ion Collider (EIC) project detector, which will be the first experiment at the collider. Positioned at the IP6 interaction region of the EIC accelerator, ePIC is poised to play a pivotal role in unraveling fundamental mysteries within the structure of visible matter by matching the whole scientific scope of the EIC project. To this end, ePIC measurements aim to address some of the most profound questions surrounding the emergence of nuclear properties by precisely imaging gluons and quarks inside protons and nuclei.

        The ePIC detector technologies will enable intricate measurements of inclusive and semi-inclusive Deep Inelastic Scattering, as well as exclusive processes in electron-ion collisions. The ambitious physics goals and the constraints imposed by the challenging collider lattice result in the detector design, where several up-to-date and novel detector approaches have been selected.

        The presentation will provide an overview of the ePIC detector related to its physics motivation, detailing its current status and outlining the innovative approaches in detector concepts and technologies that are being adopted.

        The CLAS12 luminosity upgrade and future physics opportunities

        The CEBAF Large Acceptance Spectrometer, CLAS12, in Hall B at Jefferson Lab runs experiments with a multitude of unpolarized and polarized targets using electron beams of 2 GeV to 11 GeV energies at close to the design luminosity of $L=10^{35}$ cm${-2}$ sec$^{-1}$. Since its commissioning in early 2018, CLAS12 has successfully executed a physics program that covers a broad range of topics in nuclear physics.

        The necessity of high statistics data in multidimensional kinematic phase space became evident with the analysis and publication of the first cutting-edge results on nucleon and nuclear structure. To address this demand, we plan to upgrade CLAS12 to run at higher luminosities. The first stage of the upgrade, currently in progress, aims at improving the tracking efficiency in the forward region of polar angles, with a near-term goal of reaching a production luminosity of $L=2\times 10^{35}$ cm${-2}$ sec$^{-1}$. This upgrade will fulfill the requirements of the already approved experiments. The second stage of the upgrade aims at reaching luminosities of $L>10^{37}$ cm${-2}$ sec$^{-1}$, which will open the opportunity for studying new physics topics, such as Double Deeply Virtual Compton Scattering (DDVCS), accessible only with a high-luminosity, large-acceptance detector.

        In this talk, the current performance of CLAS12, details of the upgrades to higher luminosities, and the new physics opportunities that these upgrades will open are discussed.

        SoLID: A Detector at the Luminosity Frontier.

        The Solenoidal Large Intensity Device (SoLID) is a large acceptance detector capable of operating at the luminosity frontier. It was proposed to fully exploit the potential of the continuous electron beam accelerator facility (CEBAF) 12 GeV energy upgrade at Jefferson Lab. The pillars of its scientific program consist of a series of Semi-Inclusive Deep Inelastic Scattering (SIDIS) experiments to explore the transverse-momentum dependent parton distributions of the nucleon (TMDs) at a new level of precision and provide quark momentum tomography of the nucleon internal structure, a parity-violating deep inelastic scattering (PVDIS) experiment to explore physics beyond the standard model, and a near-threshold $J/\psi$ photo- and electro-production experiment to determine the gluonic gravitational form factors and address the origin of the nucleon mass. I will discuss the need and virtues of SoLID and its potential impact on the science program of hadronic physics and physics beyond the standard model.

        Calorimetry for the ePIC Experiment

        The EIC will deliver collisions of electrons with protons and nuclei at a wide variety of energies and at luminosities up to 1000 times higher than HERA. Precisely measuring both the scattered electron and the hadronic final state is crucial for the physics of the EIC, necessitating unique designs for the electromagnetic and hadronic calorimeters in the backward, central, and forward regions. To ensure maximal containment of energy and acceptance for the required physics processes, the ePIC detector employs calorimetry over almost the entire polar angle. This talk will provide an overview of the current calorimeter designs being employed in ePIC.

        A 2nd Detector for the Electron-Ion Collider

        The Electron-Ion Collider (EIC) is the next-generation US-based project for QCD and nuclear science. It will collide polarized electrons with polarized protons and light ions, as well as heavier ions across the full mass range, at a high luminosity, over a wide range of c.m. energies. The first detector (ePIC) will support a broad science program, but having two detectors would significantly expand the capabilities of the EIC. The possibility to cross check results between the two detectors will enhance its discovery potential, and as in the case of H1 and ZEUS, combining data could reduce the overall systematic uncertainties. The latter will be even more relevant for the EIC, since once the luminosity ramps up to its nominal value, most measurements will be limited by systematics. And those that require the highest luminosities (e.g., exclusive reactions and tomography of nucleons and nuclei) would greatly benefit from an improved far-forward near-beam acceptance, which is the main feature of the interaction region where the 2nd detector could be located. The ability to detect almost all nuclear fragments in reactions where the nucleus breaks up and a recoiling light nucleus in coherent processes will also enhance the nuclear part of the EIC program. The 2nd detector will also provide complementary capabilities to ePIC in other areas (e.g., improved muon detection), and will benefit from the ongoing Generic EIC Detector R&D program.

Polarized deuteron and helium-3, as well as unpolarized ion beams from Carbon to Uranium, will be also available at the EicC. The main foci of the EicC will be precision measurements of the structure of the nucleon in the sea quark region, including 3D tomography of nucleon; the partonic structure of nuclei and the parton interaction with the nuclear environment; the exotic states, especially those with heavy flavor quark contents. The status and prospects of the EicC project will be presented in this talk.

        Backward DVCS on the pion in Sullivan processes

        The purpose of this work is to do a systematic feasibility study of measuring in backward region deeply virtual Compton scattering on the pion in Sullivan processes in the framework of collinear QCD factorization where pion to photon transition distribution amplitudes (TDAs) describes the photon content of the $\pi$ meson. Our approach employs TDAs based on the overlap of light front wave functions, using a previously developed pion light-front wave function and deriving a consistent model for the light front wave functions of the photon. Our results for the TDAs are compared with previous models found in the literature. This work is expected to lead us to an estimate of the cross-sections that could be measured in the future U.S. and China's electron ion colliders, once the computations are completed. It will also provide a comparison with the forward Sullivan DVCS case, for which a strong signal is expected.

        Impact of Inclusive Electron Ion Collider Data on Collinear Parton Distributions

        A study is presented of the impact of simulated inclusive Electron Ion Collider Deep Inelastic Scattering data on the determination of the proton and nuclear parton distribution functions (PDFs) at next-to-next-to-leading and next-to-leading order in QCD, respectively. The influence on the proton PDFs is evaluated relative to the HERAPDF2.0 set, which uses inclusive HERA data only, and also relative to the global fitting approach of the MSHT20 PDFs. The impact on nuclear PDFs is assessed relative to the EPPS21 global fit and is presented in terms of nuclear modification ratios. For all cases studied, significant improvements in the PDF uncertainties are observed for several parton species. The most striking impact occurs for the nuclear PDFs in general and for the region of high Bjorken x in the proton PDFs, particularly for the valence quark distributions.

A potentially world-leading level of precision is achievable when combining simulated inclusive neutral current EIC data with inclusive charged and neutral current measurements from HERA, with or without the addition of HERA inclusive jet and dijet data. The result can be obtained with substantially less than one year of projected EIC data at the lower end of the EIC centre-of-mass energy range. Some questions remain over the magnitude of uncertainties due to missing higher orders in the theoretical framework.

        Overview of the MOLLER experiment at JLab

        The MOLLER experiment has been designed to significantly expand the reach for new dynamics beyond the Standard Model of electroweak interactions. Using the high intensity, high precision electron beam at Jefferson Lab, MOLLER will measure the parity-violating asymmetry $A_{PV}$ in the scattering of longitudinally polarized electrons off unpolarized electrons to an overall fractional accuracy of 2.4%. This measurement will be the most sensitive probe of new flavor- and CP-conserving neutral current interactions in the leptonic sector until the advent of a linear collider or neutrino factory. The collaboration has begun fabrication of the required apparatus, with an assembly expected to complete in JLab's experimental Hall A in 2026. The experimental design will be reviewed, along with the updated status and plans for executing the measurement.

        The aim of the upcoming MOLLER experiment at Jefferson Laboratory, a national accelerator facility, is to probe electroweak interactions with unprecedented sensitivity reach at both low and high energy scales to discover new beyond the Standard Model dynamics. MOLLER is an extremely precise measurement of parity violation in electron scattering searching for new neutral currents in electron-electron scattering. The measurement relies on a high precision comparison of scattering rates for opposite beam helicity polarization, and ensuring tight limits on polarization-dependent asymmetries in the electron beam is a key technical challenge. This talk will be geared towards describing techniques to be employed to meet the stringent systematic uncertainty goals arising from beam asymmetries in parity experiments for thee upcoming MOLLER experiment.
