The possibility of a sizable, direct CP-violating asymmetry in B^-+ -> K^-+ eta

Abstract

The likelihood of a sizable, direct CP-violating asymmetry in the decays $B^{\mp }\to K^{\mp }\eta$, is calculated within the framework of the model which originally predicted a sizeable asymmetry in ${\pi }^{\mp }\eta ({\eta }^{\prime })$. It is shown in a transparent manner that these decays are the best places for providing the first clear evidence for direct CP violation in the decays of a charged particle. These decays contain two amplitudes of comparable magnitude, with different weak-interaction phase, and with different strong-interaction phase which is explicitly calculated in a model of three coupled channels of physical hadrons.
