Hadronic final states in DIS with Sherpa

Abstract

We present an extension of the multi-purpose Monte-Carlo event generator Sherpa for processes in deeply inelastic lepton-nucleon scattering. Hadronic final states in this kinematical setting are characterised by the presence of multiple kinematical scales, which were up to now accounted for only by specific resummations in individual kinematical regions. An extension of a known method for merging truncated parton showers with higher-order tree-level matrix elements allows to obtain predictions which are reliable in all kinematical limits.
