BHAGEN-1PH: a Monte Carlo event generator for radiative Bhabha scattering Original Research Article

BHAGEN-1PH is a FORTRAN program providing fast Monte Carlo event generation of the process e+e− → e+e−γ, within electoweak theory, for both unpolarized beams and also for the longitudinally polarized electron beam. The program is designed for final leptons outside a small cone around the initial leptons direction and has a new algorithm allowing also for a fast generation of noncollinear initial and final emission, as well as for asymmetric and different angular cuts for final leptons.
