CP violation in decay rates of charged bottom mesons


In the standard theory we discuss a mechanism of interference between two different tree-level charged current amplitudes to induce CP violation. The asymmetry between conjugate Cabibbo disfavoured modes of charged bottom meson decays is considered. Estimates for two-body decays ofB u andB c are presented. We find thatB u D +D *0 , for instance, can give a big CP asymmetry with values ≈1–50%, depending on the angle and phase parameters.
