摘要：

We present high-statistics results for neutral B-meson mixing and heavy-light-mason leptonic decays in the quenched approximation from tadpole-improved clover actions at beta = 6.0 and beta = 6.2. We consider quantities such as B-Bd(s) , f(Dd(s)) , f(Bd(s)) and the full Delta B = 2 matrix elements as well as the corresponding SU(3)-breaking ratios. These quantities are important for determining the CKM matrix element \V-td\.
