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
