Abstract

Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we present the first full angular analysis in the color-suppressed modes B →J/ψK and B →J/ψK . This leads to a complete determination of the decay amplitudes of these modes including the longitudinal polarization γ /γ=0.52±0.07±0.04 and the P wave component |P| =0.16±0.08±0.04. In addition, we update the branching fractions for B→J/ψK and B→J/ψK . © 1997 The American Physical Society. 0 *0 + *+ 2 * L
