Regular parallel talk WG4: QCD with Heavy Flavors and Hadronic Final States WG4


Daniel Reichelt (Durham University)


The possibility to reanalyse data taken by the HERA experiments offers the chance to study modern QCD jet and event-shape observables in deep-inelastic scattering. In this talk I will present resummed and matched predictions for the event shapes 1-jettinesss [1] and invariant mass including the effect of grooming the hadronic final state using the soft-drop technique. Non-perturbative corrections from hadronisation are taken into account through parton-to-hadron level transfer matrices extracted from dedicated Monte Carlo simulations with Sherpa, including uncertainties extracted from replica tunes to data from the HERA experiments. I will present results corresponding to the H1 setup that is equivalent to preliminary experimental analyses of those observables.
