Study of Rare B Meson Decays at Belle

Abstract

In this paper, we briefly review results on rare decays of $B$ mesons from the Belle experiment, based on 10.4 fb${}^{-1}$ data collected on the ${\rm Y}$(4S) resonance. The topics include measurements of Cabibbo suppressed decays $B\to D^{(\ast )}{K}^{(\ast )}$, charmless two-body decays $B\to \pi \pi$, $K\pi$, $KK$ and $B\to {\eta }^{{}^{\prime }}h(h=K^{+},{\pi }^{+},K^0)$, and a search for flavor changing neutral current decays $B\to K^{(\ast )}{\ell }^{+}{\ell }^{-}$.
