摘要
We study the time dependent CP asymmetries in B-d,s(0), decays in the left-right model with spontaneous breakdown of CP. Because of the new contributions to B-0-(B) over bar(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/psi K-S and B --> phi K-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 gamma.
