Nature of problem:Radiative corrections to a process are experiment dependent. A Monte Carlo simulation of both mu+mu- and mu+mu-gamma events is ideally suited for imposing any experimental cuts. The MC program presented here improves on F.A. Berends and R. Kleiss, Nucl. Phys. B177(1981)237 in two respects: it is faster and it includes Z0 production in the GWS model. | ||

Solution method:The program decides to generate either a soft or a hard bremsstrahlung event. In both cases events are first generated according to an approximate distribution. By weighing procedure this is transformed into the exact distribution. | ||

Restrictions:The virtual corrections take only the QED part into account. Moreover, terms of order mmu/E (muon mass over beam energy) are neglected, which restricts the applicability at low energies. With this restriction the program can also be used for heavy charged leptons and after some changes in coupling constants for quarks. | ||
