Deep Inelastic Scattering with Tagged Initial State Radiation: Complete O(alpha) leptonic QED Corrections
In this paper we extend the calculation of the QED corrections to deep
inelastic lepton-proton scattering with a tagged photon, taking into account
the full corrections on the lepton side. Comparing to previous results that
were obtained by considering only large logarithmic terms at leading and
next-to-leading accuray, we find that the difference is in general quite small,
however, it may be significant in the region of large and small .Comment: 21 pages, LaTeX2e, 2 figures. Corrected typos in eqs. (10),(18
A Monte Carlo algorithm for Multiphoton Beamstrahlung in Monte Carlo event generators
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
{\tt WOPPER}, that calculates the QED radiative corrections to the process
~fermions through resonating W pairs.Comment: 9 pages, LaTeX, 2 figures, uses epsfig.st
