3. Parton distribution functions

Tzvetalina Stavreva (LPSC)

Physique des particules

Parton distribution functions (PDFs) are of supreme importance in modern high energy physics. Firstly, they encode fundamental information on the structure of hadrons as probed in high energy reactions. Moreover, PDFs are an indispensable tool for the computation of cross sections at hadron colliders such as the LHC providing the link between the perturbatively calculable parton level cross...

22. Aspects of QCD studies at LAPTH

Francois Arleo (LAPTH)

24/05/2012 09:20

In this brief talk I will present various facets of the research carried out at LAPTh on the theory of the strong interaction (QCD), namely: - Loop calculations involving many external legs and the GOLEM library; - Prompt photon production at hadronic colliders: NLO calculations and phenomenology; - Studies on QCD at finite temperature and quark-gluon plasma formation in heavy-ion collisions.

4. Physics Beyond the Standard Model

Physique des particules

We highlight some of the shortcomings of the Standard Model and explain why we expect to find new physics around the TeV scale at the Large Hadron Collider (LHC) at CERN. We present some well-motivated scenarios for physics beyond the Standard Model like supersymmetry, grand unification, new gauge symmetries, extra dimensions and string theory, and show how our work at LPSC contributes to...

5. The life and times of Supersymmetry

Suchita Kulkarni (LPSC)

Physique des particules

The ongoing quest for finding what exists beyond the Standard Model of particle physics is driven by many of the observed phenomena like the dark matter, the origin of neutrino masses or the origin of the matter-antimatter asymmetry in the early universe. One of the most elegant extensions of the Standard Model of particle physics is Supersymmetry. It is theoretically well motivated and...

23. Research in Astrophysics and Cosmology at LAPTh

Pasquale Serpico (LAPTH)

24/05/2012 11:00

I will briefly review the composition and the activities of the astrophysics and cosmology group at LAPTh. A sketch will be given of two representative topics of research in the two areas, namely indirect dark matter searches (and connections with cosmic ray astrophysics problems) and neutrino cosmology.

2. Higgs and Dark Matter in SUSY

Guillaume Drieu la Rochelle (LAPTH)

Physique des particules

Supersymmetry, being one of the most mainstream extensions of the Standard Model, is now being probed to a high level in different experimental studies. Though the direct searches for superpartners at the LHC are still confined to put lower bounds on squarks, it may not be the case in the Higgs sector, and on the other side the experimental searches for dark matter are getting sensitive to the...
