Measurement of the helicity suppressed ratio of charged kaon leptonic decay
rates BR(K --> e nu)/BR(K --> mu nu) has long been considered as an excellent test
of lepton universality and of the Standard Model (SM) description of weak
interactions. It was pointed recently that the suppression of the SM contribution
might enhance the sensitivity to SUSY-induced effects to an...

In view of the new NA62 measurement of R_K = Gamma(K -> e nu)/Gamma(K -> mu nu) probing lepton flavour universality with an unprecedented precision, I critically discuss supersymmetric contributions to this observable. The MSSM corrections to R_K are constrained using the anomalous magnetic moment of the electron a_e and the renormalisation of its mass m_e. Neither of these quantities has been...

MEG, Mu-E-Gamma, is an experiment aiming to detector a lepton-flavor violating muon decay, mu-->e gamma, with a better sensitivity than that of the previous experiment. The ultimate goal of the MEG experiment is to reach the sensitivity of the Br(mu->e gamma) at 10^13. Recently we have published our first result obtained using 2008 data, setting the branching ratio limit of 2.8x10^-11 at 90%...

We study the impact of a type-I SUSY seesaw concerning flavour violation (LFV) both at low energies and at the LHC. The study of the dilepton invariant mass distribution at the LHC allows to reconstruct some of the masses of the different sparticles involved in a decay chain (with an expected precision around the percent level). If slepton mass splittings are interpreted as due to the...

Sneutrino-antisneutrino oscillation can be a very useful probe to look for signatures of lepton number violation ($\Delta L$ = 2) at the LHC. Here, we discuss the effect of the boost factor $\gamma$ and the travelling distance $L$ on the probability of the oscillation. We demonstrate that these two parameters can significantly alter the probability of the oscillation when the sneutrinos are...

After a brief introduction of the two Higgs doublet models, we compare the
effectiveness of the two hypotheses of Natural Flavor Conservation and Minimal Flavor Violation, in suppressing the strength of flavor changing neutral currents. The phenomenological implications of the Minimal flavor violating scenario are discussed. Particular focus is given to the CP-violating asymmetry of the Bs...
