论文摘要
B_C介子是用于探测重型夸克物理的实验室。此外,它们会腐烂成charmonia,因此它们的衰变可用于分析可能的外来炭。在这项工作中,使用光锥QCD总规则(LCSR)分析了B_C介子中B_C中的半衰减衰减。 Charmonia的分布幅度取自夸克模型计算。将获得的基态衰减率和激发的charmonia与文献中的结果进行了比较。
B_c mesons are laboratories for probing heavy quark physics. Furthermore, they decay into charmonia and hence their decays can be used to analyze possible exotic charmonium. In this work, the semileptonic decays of B_c mesons into P wave charmonia are analysed using light cone QCD sum rules (LCSR). The distributions amplitudes for the charmonia are taken from a quark model computation. The obtained decay rates for the ground state and excited charmonia are compared with the results found in the literature.
