Abstract：
The singlet-triplet mixing of ¹P₁-³P₁ is studied via calculating the branching ratios of semileptonic decay B_s→D_s1lν and B→D₁lν by means of the instantaneous Bethe-Salpeter method. Special attention is paid to the relativistic corrections, since they are large for the P-wave states. Using the Mandelstam Formalism, we compute the transition form factors not only in the high-energy lepton end-point region but also in the full Q² region. And the non-perturbative QCD effects are taken care of in the overlapping integral over the relativistic wave functions of the initial and nial states.
