Search for CP-violating charge asymmetry in B-+/- -> J/psi K-+/- decays

We present the result of a search for charge asymmetry in B-+/- -> J/psi K-+/- decays using 772 X 10(6) B (B) over bar pairs collected at the Y(4S) resonance by the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The CP-violating charge asymmetry is measured to be A(CP)(B+ -> J/psi K+) = [-0.76 +/- 0.50 (stat) +/- 0.22 (syst)]%.
