Abstract

We report an improved measurement of the partial-rate CP asymmetry in B^±→K^(-)0π^± decays. The analysis is based on a data sample of 85×10⁶ BB̄ pairs collected at the Γ(4S) resonance with the Belle detector at the KEKB e⁺e^- storage ring. We measure A _CP((K^(-)0π^± = 0.07 _{-0.08 -0.03}^{+0.09 +0.01}, where the first and second errors are statistical and systematic, respectively; the corresponding 90% confidence-level interval is -0.10 <A_CP(K^(-) ⁰π^±)<0.22.

N2 - We report an improved measurement of the partial-rate CP asymmetry in B±→K(-)0π± decays. The analysis is based on a data sample of 85×106 BB̄ pairs collected at the Γ(4S) resonance with the Belle detector at the KEKB e+e- storage ring. We measure A CP((K(-)0π± = 0.07 -0.08 -0.03+0.09 +0.01, where the first and second errors are statistical and systematic, respectively; the corresponding 90% confidence-level interval is -0.10 <ACP(K(-) 0π±)<0.22.
