Measurement of branching fractions and charge asymmetries for two-body<i>B</i>meson decays with charmonium

Abstract

We report branching fractions and charge asymmetries for exclusive decays of charged and neutral B mesons to two-body final states containing a charmonium meson, $J/\ensuremath{\psi}$ or $\ensuremath{\psi}(2S).$ This result is based on a $29.4{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric ${e}^{+}{e}^{\ensuremath{-}}$ collider.
