Lepton flavour violation in tau decays with constrainedminimal supersymmetric type-i seesaw model

The lepton flavor violation (LFV) in decays of tau lepton into elctrons and muons is studied within the constrained minimal supersymmetric standard model (MSSM) extended by Seesaw model. Assuming that the mass scale of Majorana neutrinos is much larger than the scale of supersymmetry (MR >> MSUSY). The obtained Weinberg operator is being suppressed by the large energy scale MR ~ 10^14 GeV which generates the light neutrinos masses. The decay rates for the lepton flavor violating tau lepton decays are evaluated by using the supersymmetric high scale seesaw models. The value of the upper limit of the branching ratio of tau into muon-electron decays will be set and compared with the sensitivity of the future colliders.
