The possibility of a sizable, direct CP-violating asymmetry in B±→K±η

The likelihood of a sizable, direct CP-violating asymmetry in the decays B±→K±η, is calculated within the framework of the model which originally predicted a sizable asymmetry in π±η(η'). 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
