title = "Search for CP Violation in B± → ψ K± and B± → ψ(2S) K± dacays",
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 × 106 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±.",
