Electroweak Penguin B Decays at Belle

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.Comment: Proceeding for EPS 2003, Aachen, Germany, July 17 - 23, 200
