This vertex is characterized by only one coupling constant which is computed through the analysis of the J/ψ → γπ 0 decay. Assuming ρ meson dominance we compute the BR(J/ψ → π 0 π + π −), finding a good agreement with the experimental measurement.

We propose a flavor extended MSSM by considering a hierarchical family structure for the trilinear scalar Soft-Supersymmetric terms of the Lagrangian, present at the SUSY breaking scale. We obtain analytical results for the rotation mass matrix, with the consequence of having non-universal slepton masses and the possibility of leptonic flavour mixing. The one-loop supersymmetric contributions to the leptonic flavour violating process τ → µγ are calculated in the physical basis, instead of using the well known Mass Insertion Method. The flavor violating processes BR(l i → l j γ) are also obtained, in particular τ → µγ is well within the experimental bounds. We present the regions in parameter space where the muon g-2 problem is either entirely solved or partially reduced through the contribution of these flavor violating processes.
