Abstract

We present an exact calculation of the process e+ee+eγ to order g3, that is, including the γ and Z0 intermediate vector bosons and keeping fermion masses. This condition is needed to study the contribution of this process as background to single photon events. The calculation has been done at the amplitude level and the strong peaks occurring in the matrix element squared for the single photon configuration have been absorbed by an adequate mapping of the phase space variables. These two facts are necessary in order to obtain a numerically stable integration and an efficient Monte Carlo generator.
