摘要：
The likelihood of a sizable, direct CP-violating asymmetry in the decays B-/+ --> K(-/+)eta, is calculated within the framework of the model which originally predicted a sizable asymmetry in pi(-/+) eta(eta'). 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.
