在朴素分解假设下，研究了从$\bar B^{0}_s$和$\bar B^0$到轨道激发p波粲介子的非轻子衰变。基于Mandelstam形式，在改进的Bethe-Salpeter方法的框架下，计算了衰变$\bar B^0_s\rightarrow D^{(*)+}_{sJ}X^-$和$\bar B^0\rightarrow D^{(*)+}_{J}X^-$$(X = \pi, \rho, K, K^*, D, D^*, D_s, D^*_s)$的强子矩阵元，其中通过对初始和最终状态的相对论性Salpeter波函数的重叠积分很好地考虑了非微扰QCD效应。其中一些衰变具有相当大的分支分数，预计将在当前和不久的将来的实验中被检测到。
The nonleptonic decays from $\bar B^{0}_s$ and $\bar B^0$ to an orbitally excited P-wave charmed meson are studied within the naive factorization hypothesis. Based on the Mandelstam formalism, and under the framework of the improved Bethe–Salpeter method, the hadronic matrix elements of the decays $\bar B^0_s\rightarrow D^{(*)+}_{sJ}X^-$ and $\bar B^0\rightarrow D^{(*)+}_{J}X^-$ $(X = \pi, \rho, K, K^*, D, D^*, D_s, D^*_s)$ are calculated, in which nonperturbative QCD effects are well considered by overlapping integral over the relativistic Salpeter wave functions of initial and final states. Some of these decays have sizable branching fractions and are expected to be detected in the current and near future experiments.
