摘要：

A new event generator for lepton pair production and wide angle Bhabha scattering, BHAGENE3, is presented. Both electroweak and higher order (beyond O(alpha)) QED corrections are included. Comparisons are made with results from the programs, based on the structure function formalism, ALIBABA, TOPAZ0 and ZFITTER. For the case of the final states l+l-gammagamma (l = e, mu, tau) BHAGENE3 results are compared with those of Monte Carlo generators that use the exact O(alpha2) amplitudes.
