Abstract. The branching ratio for the μ → eγ decay in the framework of MSSM with minimal flavour violation in the MSSM is presented for various regions of the mSUGRA parameter space. The impact of right-handed neutrinos and their superpartners is discussed considering SUSY-seesaw mechanism of type I. The lepton flavour violation goes through the PMNS mixing matrix. The dependence on tanβ is studied in comparison with the experimental data. The results crucially depend on the mixing angle θ₁₃. Observation of this decay would serve as a manifestation of new physics beyond the SM.
