Large tan(beta) effects in flavour physics

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 $\text{BR}(P\to \mathrm{\ell }\nu )$, $\text{BR}(B_{s,d}\to {\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-})$ and $\text{BR}(\mu \to e\gamma )$
