Lepton flavour violation in tau decays with constrained minimal supersymmetric Type-I seesaw model

This thesis presents a study of the analysis of the Lepton Flavor Violation (LFV) of tau decays τ → e γ and τ → μ γ . Here we focus on the Minimal Supersymmetric Standard Model (MSSM) extended by Seesaw Type-I Model, with three right-handed neutrinos and their Supersymmetric Standard Model (SUSY) partners. Experiments have shown that the violation of the lepton flavor so far is only in the neutrino sector. Therefore, we predict it to happen in the charged lepton sector.
