B_c介子半轻子衰变到P波χ_c态或h_c态

B_c Meson Semileptonic Dacays to P Wave x_c or h_c State

计算 Bc介子半轻子衰变 ,末态强子是 P波χc态或 hc态的过程 .利用势模型理论求解介子波函数和质量 .强子矩阵元写成形状因子的形式 。

The semileptonic B c decays to P wave x c or h c are presented. The wave function and mass of meson are obtained by potential model, write the hadronic matrix element in the form of form factors, and express the form factors in terms of the overlap integrals of bound states wave functoins of the initial and finial mesons.
