Title of program: DIAG36 Catalogue Id: AAFH_v1_0 Nature of problem Four-lepton processes such as e^+e^- -> e^+e^+e^-e^-, e^+e^- -> e^+e^-mu^+mu^-, e^+e^- -> mu^+mu^+mu^-mu^-, e^+e^- -> mu^+mu^-tau^+tau^- are described by a (sub) set of 36 Feynman diagrams. In the e^+e^- -> e^+e^+e^-e^- case all these graphs contribute and give rise to 657 different peaks of the differential cross section in a seven dimensional phase-space. The MC program presented here can produce unweighted events for these processes, while all masses and peaks are properly taken into account. Moreover, it can also be used ...
