Semileptonic Production of Scalar and Tensor p-Wave Charmed Mesons

With the same constituents of quark and antiquark,the p-wave state has a higher mass than the corresponding s-wave state,but the relativistic corrections are much larger in the processes of which p-wave mesons are involved.Considering this,the relativistic Bethe-Salpeter method is applied to estimate the branching fractions of semileptonic decays B（s） D（sJ）* lv（J = 0,2）.Our predictions are Br[Bs0 → Ds0*+（2317）l-v]- 0.50%,Br[Bs0 → Ds2*+（2573）l-v]= 0.40%,Br[B-→ D0*0（2400）l-v]= 0.79%,Br[B-→ D2*+（2460）l-v]= 0.28%,Br[B0 → D0*+（2400）l-v]= 0.58%and Br[B0 → D2*+（2460）l-v]= 0.27%.
