摘要：

We reexamine the right-handed current effects in b -> s transitions in nonmanifest left-right models. Using the effective Hamiltonian approach including all possible low-energy operators, we obtain especially the B -> K pi decay amplitudes including annihilation contributions, and investigate the right-handed current contributions to CP asymmetries in B -> K pi decays. Taking into account the constraints from global analysis of muon decay measurements, vertical bar V-ub vertical bar measurements in inclusive and exclusive B decays, and B-s(0) - (B) over bar (0)(s) mixing measurements, we find the allowed regions of new physics parameters satisfying the current experimental data.
