| 概要 | K. Abe, S. Okuno, et al. [Belle Collaboration] , We search for direct CP violation in flavor specific B → Kπ decays by measuring the rate asymmetry between charge conjugate modes. The search is performed on a data sample of 11.1 × 106B{B} events recorded on the υ(4S) resonance by the Belle experiment at KEKB. We measure 90% confidence intervals in the partial rate asymmetry ACP of －0.25 ＜ ACP(K∓π± ＜ 0.37, －0.40 ＜ ACP(K∓π0) ＜ 0.36, and －0.53 ＜ ACP(K0π∓) ＜ 0.82. By combining the K∓π± and K∓π0 final states, we conclude that －0.22 ＜ ACP(K∓(π± + π0)) ＜ 0.25 at the 90% confidence level. |
