Description
In the light of the recent measurement by the BES Collaboration, the two-body decays of J/ψ and ψ' into an axial-vector meson and a pseudoscalar meson are analyzed in the framework of the KA-KB mixing including substantial SU(3) and G parity violations due to one-photon annihilation. A somewhat puzzling pattern of the K1+K- decay channel can be understood with no tight constraint on the mixing angle. The ratio of K10(1400)bar K0 to K10(1270)bar K0 will be the cleanest source of information to determine the mixing angle from the 1+0- decays in the presence of one-photon annihilation. copyright 1997 The American Physical Society
