Supersymmetric Lepton Flavour Violation and Neutrinos mass textures : an update

Abstract

We revise the prospects for the observation of charged lepton avour violation (LFV), in the light of the recent results from the LHC, MEG and neutrino experiments. We work in the context of the Minimal Supersymmetric Standard Model (MSSM) extended with massive neutrinos arising from a see-saw mechanism. The connection between the observed neutrino oscillations with avour oscillations in the charged sector is established using a model for the Yukawa couplings arising from a SU(5) grand uni ed theory (GUT) with Abelian avour symmetries. We discuss in this scenario the possible observation on the radiative decays ! e and !

and LFV processes that could be detectable at a linear collider (LC) with a centre-of-mass energy in the TeV range.
