Abstract

We describe a simple algorithm that calculates the distributions of electrons and positrons under multiphoton beamstrahlung at a future linear collider. The evolution equation as given by Chen is solved by a Monte Carlo algorithm. Explicit multiple beamstrahlung photons are generated. We present first results from an implementation of beamstrahlung into the Monte Carlo event generator WOPPER, that calculates the QED radiative corrections to the process e+e- 4~fermions through resonating W pairs.
