Bs decays: CP asymmetries in left-right models with spontaneous CP violation

Abstract

We present the contributions of new CP phases in CP asymmetries of two-body neutral $B_s$ decays coming from a left--right model with spontaneous CP violation. Large deviations from the Standard Model predictions can be accommodated in a natural way by this type of models. The new physics effects on the mixing, width difference and decays are analysed. In particular, we show how the measurement of the angle $\gamma$ in electroweak penguin-dominated processes can be largely affected.
