Potential for observable deviations in P→ℓν branching ratios

Abstract

After a short introduction to the SUSY flavour problem, we focus the attention on the MSSM with MFV and large $\tan\beta$. The theoretical motivations and the general features of this scenario are briefly reviewed. The possible signatures in low-energy flavour-violating observables are discussed, with particular attention to the role played by $\BR(P\to\ell\nu)$, $\BR(B_{s,d}\to \ell^+\ell^-)$ and $\BR(\mu\to e \gamma)$
