Abstract

We present the result of a search for charge asymmetry in B ^±→J/ψK^± decays using 772×106 BB̄ pairs collected at the Υ(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/ ψK⁺)=[-0.76±0.50(stat)±0.22(syst)]%.
