英文摘要We search for direct CP violation in flavor specific B -->K pi decays by measuring the rate asymmetry between charge conjugate modes. The search is performed on a data sample of 11.1 x 10(6) B(B) over bar events recorded on the Y(4S) resonance by the Belle experiment at KEKB. We measure 90% confidence intervals in the partial rate asymmetry A(CP) of - 0.25) pi (+/-)) <0.37, - 0.40) pi (+/-) and K(+/-) pi (0) final states, we conclude that -0.22 )(pi (+/-) +pi (0)))<0.25 at the 90% confidence level.
