Abstract

We present a search for direct CP violation in B → J/ψK and B → ψ(2S)K decays. In a sample of 9.7 × 10 BB meson pairs collected with the CLEO detector, we have fully reconstructed 534 B → J/ψK and 120 B → ψ(2S) K decays with very low background. We have measured the CP-violating charge asymmetry to be [+0.8 ± 4.3 (sat) ± 0.4 (syst) ]% for B → J/ψK and [+2.0 ± 9.1(sat) ± 1.0 (syst)]% for B → ψ(2S)K . © 2000 The American Physical Society. ± ± ± ± 6 ¯ ± ± ± ± ± ± ± ±
