An Analytic Initial State Parton Shower — Wolfgang Kilian2, Jürgen Reuter1, and •Sebastian Schmidt1 — 1DESY, Standort Hamburg — 2Universität Siegen
We present an algorithm for a refined version of a final-state parton shower and a completely new one for an initial-state shower. These showers allow to reweight shower histories, as the complete weights for the showered events are explicitly known. We compare these algorithms using an implementation in the event generator WHIZARD to results from existing showers as well as data from the LEP, Tevatron and LHC colliders.
