Abstract
Besides the fact that the SM has to be extended in order to account for neutrino masses, an interesting implication of this discovery is the violation of flavour symmetry in the leptonic sector. This feature is known as lepton flavour violation (LFV), and in principle, it could allow processes such as li --> ljγ to occur when i ≠ j. This work focuses on the calculation of Br(h --> eµ) in the Minimal Supersymmetric Standard Model (MSSM) with broken R-parity, which is a symmetry that implies both lepton and baryon number. If the latter is conserved to prevent proton decay, this theory is very well suited to describe tiny(eV) neutrino masses, and further more, LFV processes are enhanced via R-parity violating (RpV) parameters, which sets a good scenario for probing physics beyond the SM. Our preliminary results show that for two working scenarios where ML = 2 TeV and 10 TeV, Br(h --> eµ) cannot exceed the value of 10−10 (respectively 10−7) if neutrino constraints are satisfied.
