Search for CP-violating charge asymmetry in B<sup>±</sup>→J/ ψK<sup>±</sup> decays
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 ACP(B+→J/ ψK+)=[-0.76±0.50(stat)±0.22(syst)]%. © 2010 The American Physical Society.
