Measurement of the Decay Amplitudes and Branching Fractions of $B\to J/\psi K^{\ast }$ and $B\to J/\psi K$ Decays

Abstract

Using data taken with the CLEO II detector, we present the first full angular analysis in the color-suppressed modes B0 --> J/psi K*0 and B+ --> J/psi K*+. This leads to a complete determination of the decay amplitudes of these modes. In addition, we update the branching fractions for B --> J/psi K and B --> J/psi K*.
