Hadronic final states in deep-inelastic scattering with Sherpa
Tancredi Carli, Thomas Gehrmann, Stefan Höche
We extend the multi-purpose Monte-Carlo event generator Sherpa to include processes in deeply inelastic lepton-nucleon scattering. Hadronic final states in this kinematical setting…
Hard photon production and matrix-element parton-shower merging
Stefan Hoeche, Steffen Schumann, Frank Siegert
We present a Monte-Carlo approach to prompt-photon production, where photons and QCD partons are treated democratically. The photon fragmentation function is modelled by an interle…
QCD matrix elements and truncated showers
Stefan Hoeche, Frank Krauss, Steffen Schumann +1
We derive an improved prescription for the merging of matrix elements with parton showers, extending the CKKW approach. A flavour-dependent phase space separation criterion is prop…
