In Physsim generator, the range of the decay mode identification number ( see sub Sec.1.2). for W and Z decay can be specified in the file, jsf.conf. The name of parameters are, ENWBases.WpModesLo and ENWBases.WpModesHi in the case of ENW generator and ZZBases.Z1ModesLo, ZZBases.Z1ModesHi, ZZBases.Z2ModesLo and ZZBases.Z2ModesHi in the case of ZZ generator. These parameter specify the lower limit and upper limit of allowed decay mode of W and Z. The sample files are $(KFLIBROOT)/wz/ENWStudy/prod/jsf.conf and $(KFLIBROOT)/wz/ZZStudy/prod/jsf.conf. The other generators have also similar name of parameters.
