Contribution

It provides the first observations of specific B decay modes and reports on searches for rare decays and CP asymmetries, advancing understanding of FCNC processes.

Findings

First observation of B->K*l+l- decay

First observation of B->phi K gamma decay

Observation of inclusive B->Xs l+l- decay

Abstract

We summarise the most recent results of the Belle experiment about flavour changing neutral current (FCNC) radiative and (semi-) leptonic B decays. In particular, we report about the first observation of the decays B->K*l+l-, B->phi K gamma, the inclusive B->Xs l+l-$. We also report about searches for B->l+l- decay and for CP asymmetries in B->K*gamma.
