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)lν (J=0,2). Our predictions are BrB⁰_s→D^*+_s0(2317)l^?ν=0.50%, BrB⁰_s→D^*+_s2(2573)l^?ν=0.40%, BrB^?→D^*0₀(2400)l^?ν=0.79%, BrB^?→D^*0₂(2460)l^?ν=0.28%, BrB⁰→D^*+₀(2400)l^?ν=0.58% and BrB⁰→D^*+₂(2460)l^?ν=0.27%.
