Description
The current measurements of CP asymmetries in B -> K pi decays are in disagreement with the predictions of the Standard Model. In order to solve this discrepancy, using the effective Hamiltonian approach, we investigate the right-handed current contributions to B -> K pi decay amplitudes including all possible low-energy operators in the nonmanifest left-right model. We find the allowed region of new physics parameters satisfying the current experimental data, and discuss its implication to other observables such as Bs mixing and the branching fraction for B -> tau nu decays.
