Abstract

Color-suppressed decays of B mesons to final states with ψ(2S) mesons have been observed with the CLEO detector. The branching fractions for the decays B →ψ(2S)K , B →ψ(2S)K*(892) , B →ψ(2S)K , and B →ψ(2S)K*(892) are measured to be (7.8±0.7±0.9)×10 , (9.2±1.9±1.2)×10 , (5.0±1.1±0.6) × 10 , and (7.6±1.1±1.0)×10 , respectively, where the first uncertainty is statistical and the second is systematic. The first measurement of the longitudinal polarization fraction is extracted from the angular analysis of the B→ψ(2S)K*(892) candidates: Γ /Γ = 0.45±0.11±0.04. Our measurements of the decays B →ψ(2S)K and B →ψ(2S)K*(892) are first observations. © 2001 The American Physical Society. + + + + 0 0 0 0 -4 -4 -4 -4 0 0 + + L
