摘要:
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%.
