英文摘要The (B) over bar (0)(s) -> D(s)((*)+)l(-)(nu) over bar (l) semileptonic decays were calculated in the framework of the standard model by employing the perturbative QCD (pQCD) factorization approach. We defined four ratios of the branching ratios of the considered decays R(D-s((*))) and R-Ds(l,tau). From the numerical results and phenomenological analysis we found that (a) the pQCD predictions for the branching ratios Br((B) over bar (0)(s) -> D(s)((*)+)l(-)(nu) over bar (l)) generally agree well with the previous theoretical predictions, (b) for the four ratios, the pQCD predictions are R(D-s) = 0.392 +/- 0.022, R(D-s*) = 0.302 +/- 0.011, R-Ds(l) =0.448(-0.041)(+0.058), and R-Ds(tau) = 0.582(-0.045)(+0.071), which show a very good SUd3_F flavor symmetry with the corresponding ratios for B -> D((*))l(-)(nu) over bar (l) decays, and (c) we strongly suggest the measurements of the new ratios R(D-s((*))) and R-Ds(l,tau) in the forthcoming Super-B experiments.
