Abstract

We discuss the perspectives of testing the right-handed Majorana mass scale M_R of the SUSY see-saw model in the mSUGRA framework. Lepton-flavor violating low energy processes are analyzed in recently proposed post-LEP benchmark scenarios, taking into account present uncertainties and future developments in the neutrino sector. Nonobservation of mu -> e gamma in the next-generation PSI experiment will provide upper bounds on M_R of the order of 10^(12-14) GeV, while on the other hand, a positive signal for tau -> mu gamma at SUPERKEKB or the LHC may determine M_R for a given mSUGRA scenario with an accuracy of a factor of 2.
