Mixing induced CP asymmetries in b → sγ decay and spontaneous CP violation Original Research Article

We analyze the mixing induced CP asymmetry in the decay b → sγ in the left-right symmetric model with spontaneous CP. This model possesses the useful property that all the CP-violating observables can be expressed in term of a single phase, a ratio of scalar vevs, quark masses and weak mixing angles but not on unconstrained quantities such as Yukawa coupling or additional phases. The calculated CP asymmetry can be much larger than in the Standard Model.
