本文研究了BaBar合作组和LHCb合作组观测到的新态DsJ(3040)和DJ(3000)的产生。在我们的工作中,我们假设这些态是量子数JP = 1+的Ds(2 P)和D(2 P)态。改进的Bethe-Salpeter(BS)方法的结果表明,通过Bs和B衰变到DsJ(3040)和DJ(3000)的半轻子衰变具有相当大的分支比,如Br(Bs 0 → DsJ+(3040)l−ν l)= 5.79 × 10−4,Br(B 0 → DJ+(3000)l−ν l)= 2.63 × 10−4(l = e,μ),这表明这些半轻子衰变可以在实验中得到。
In this paper, we study the productions of the newly detected states DsJ(3040) and DJ(3000) observed by BaBar Collaboration and LHCb Collaboration. We assume these states to be the Ds(2P) and D(2P) states with the quantum number JP = 1+ in our work. The results of improved Bethe–Salpeter (BS) method indicate that the semi-leptonic decays via Bs and B into DsJ(3040) and DJ(3000) have considerable branching ratios, for example, Br(Bs0 → D sJ+(3040)l−ν l) = 5.79 × 10−4, Br(B0 → D J+(3000)l−ν l) = 2.63 × 10−4(l = e,μ), which shows that these semi-leptonic decays can be accessible in experiments.
