CP asymmetries in B0 decays in the left-right model

Abstract

We study time dependent CP asymmetries in B^0_{d,s} decays in the left-right model with spontaneous breakdown of CP. Due to the new contributions to B^0-\bar B^0 mixing the CP asymmetries can be substantially modified. Moreover, there can be significant new contributions to the $B$-meson decay amplitudes from the magnetic penguins. Most promising for detection of the new physics in the planned $B$ factories is that the CP asymmetries in the decays B--> J/ψK_S and B--> ϕK_S which are supposed to be equal in the standard model can differ significantly in this class of models independently of the results in the measurements of B--> X_s γ.
