Abstract
Color-suppressed decays of B mesons to final states with psi (2S) mesons ha ve been observed with the CLEO detector. The branching fractions for the de cays B+--> psi (2S)K+, B+--> psi (2S)K*(892)(+), B-0--> psi (2S)K-0, and B- 0--> psi (2S)K*(892)(0) are measured to be (7.8 +/- 0.7 +/- 0.9) x 10(-4), (9.2 +/- 1.9 +/- 1.2) x 10(-4), (5.0 +/- 1.1 +/- 0.6) x 10(-4), and (7.6 +/ - 1.1 +/- 1.0) x 10(-4), respectively, where the first uncertainty is stati stical and the second is systematic. The first measurement of the longitudi nal polarization fraction is extracted from the angular analysis of the B - -> psi (2S)K*(892) candidates: Gamma (L)/Gamma = 0.45 +/- 0.11 +/- 0.04. Ou r measurements of the decays B-0 --> psi (2s)K-0 and B+--> psi (2S)K*(892)( +) are first observations.
