Implementing initial state radiation for lepton induced processes in AMEGIC++

Abstract

We have implemented the method of Yennie, Frautschi, and Suura up to first order in alpha for the simulation of QED Initial State Radiation in lepton induced processes in AMEGIC++. We consider s-channel processes via the exchange of scalar or vector resonances at electron and muon colliders.
