Description

The Belle-II experiment has recently measured $\mathcal{B}(B\to K\nu\nu)$, which appears to be almost $3\sigma$ larger than its Standard Model (SM) prediction. In this talk, I will critically revisit the status of the SM predictions for the $B\to K^{(\ast)}\nu\nu$ decays, and discuss the interpretation of this Belle-II measurement in terms of a general Effective Field Theory, as well as concrete models of physics beyond the SM.
