CP violation in quasi-inclusive B→K(*)X decays

We consider the possibility of observing CP violation in quasi-inclusive decays of the type B--->K-X, B--->K*X-, (B) over bar(0)-->K-X and (B) over bar(0)-->K*X-, when X does not contain strange quarks. We present estimates of rates and asymmetries for these decays in the standard model and comment on the experimental feasibility of observing CP violation in these decays at future B factories. We find the rate asymmetries can be quite sizeable. Observation of such asymmetries could be used to rule out the superweak model of CP violation.
