CP-violation effects in the decays B--/+ -> D*K*(-/+) and method for determining the weak phase gamma

摘要

A method for determining the angle. and the ratio of the amplitudes A(lambda)(B- -> (D) over bar*(0) K*(-)) and A(lambda)(B- -> D*(0) K*(-)), r(B lambda), for all three vector-meson polarization states by using the decays B(sic) -> D* K*(sic) is proposed. This method relies on the interference between the decays B- -> D*(0) K*(-) and B- -> (D) over bar*(0) K*(-), which arises if D*(0) and (D) over bar*(0) decay to D-0/(D) over bar (0) pi(0) and D-0/(D) over bar (0) gamma, whereupon D-0 and (D) over bar (0) mesons decay to common final hadron states. The doubly Cabibbo-suppressed modes of D-0-meson decay are chosen here to specify such final states.
