Mixing-induced CP asymmetries in inclusive B decays

We consider CP violating asymmetries that are induced by particle-antiparticle mixing in inclusive channels of neutral B meson decay. Not only are the branching ratios sizable, at the 1% to 50% level, but some of these asymmetries are expected to be large because of substantial CKM phases, The inclusive sum partially dilutes the asymmetries, but the dilution factor is calculable. Assuming local quark-hadron duality, the CKM parameters can be extracted. We discuss in detail the determination of sin 2 alpha from charmless final states in decays of B-d mesons and survey the asymmetries for other inclusive final states. The total inclusive time-dependent asymmetry, where all modes of a weakly decaying neutral meson are summed over, is non-vanishing in general and measures Im(Gamma(12)/M(12)). While probably not yet sensitive to standard model predictions, meaningful CP violation studies can be conducted with existing data samples of inclusive neutral B decays.
