Abstract.
We discuss the perspectives of testing the right-handed Majorana mass scale MR 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 \(\mu \rightarrow e \gamma\) in the next-generation PSI experiment will provide upper bounds on MR of the order of \(10^{12\div 14}\) GeV, while on the other hand, a positive signal for \(\tau \rightarrow \mu \gamma\) at SUPERKEKB or the LHC may determine MR for a given mSUGRA scenario with an accuracy of a factor of 2.
