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. Non-observation of μ → eγ in the next-generation PSI experiment will provide upper bounds on MR of the order of 10^12÷14 GeV, while on the other hand, a positive signal for τ → μγ at SUPERKEKB or the LHC may determine M_R for a given mSUGRA scenario with an accuracy of a factor of 2.
