Abstract

We report improved measurements of the partial rate asymmetry (A _CP) in B → hh decays with 140 fb ^-1 of data collected with the Belle detector at the KEKB e ⁺e ^- collider. Here h stands for a charged or neutral pion or kaon and in total five decay modes are included: K ^±π ^±, K _s ⁰π ^±, K ^±π ⁰, π ^±π ⁰, and K _s ⁰π ⁰. The flavor of the last decay mode is determined from the accompanying B meson. Using a data sample 4.7 times larger than that of our previous measurement, we find A _CP(K ^±π ^±) - 0.088 ± 0.035 ± 0.013, 2.4σ from zero. Results for other decay modes are also presented.

N2 - We report improved measurements of the partial rate asymmetry (A CP) in B → hh decays with 140 fb -1 of data collected with the Belle detector at the KEKB e +e - collider. Here h stands for a charged or neutral pion or kaon and in total five decay modes are included: K ±π ±, K s 0π ±, K ±π 0, π ±π 0, and K s 0π 0. The flavor of the last decay mode is determined from the accompanying B meson. Using a data sample 4.7 times larger than that of our previous measurement, we find A CP(K ±π ±) - 0.088 ± 0.035 ± 0.013, 2.4σ from zero. Results for other decay modes are also presented.
