Description
The transition of a strange to a down quark requires a flavour changing neutral current (FCNC) which is forbidden at tree level in the Standard Model. Consequentely, processes involving such transition are sensitive to any potential physics beyond the standard model including a FCNC. In this talk, I will present the status of lattice calculations for two such decays: the rare Kaon decay $K^+ \to \pi^+ \ell^+ \ell^-$, and the rare Hyperon decay $\Sigma^+ \to p \ell^+ \ell^-$.
