论文摘要
在这项工作中，我们使用康奈尔电位模型研究了$ l = s $，$ p $，$ d $，$ d $，$ d $，$ f $，$ f $，$ d $，$ d $，$ d $，$ p $，$ p $，$ p $，$ b_c $梅森的更高$ b_c $ mesons，使用康奈尔电位模型，这考虑了筛查效果，我们将研究更高。 $ b_c $状态的计算出的质谱与当前的实验数据达成了合理的一致性。基于光谱法，还通过应用我们的数值波函数来评估所有允许的辐射过渡和强衰变的部分宽度。将我们的结果与前者的结果进行比较，我们指出了各种模型之间的差异，并得出了本文获得的新结论。我们的理论结果对于在实验中搜索更多$ b_c $介子非常有价值。
In this work, we study higher $B_c$ mesons to the $L=S$, $P$, $D$, $F$, $G$ multiplets using the Cornell potential model, which takes account of the screening effect. The calculated mass spectra of $B_c$ states are in reasonable agreement with the present experimental data. Based on the spectroscopy, partial widths of all allowed radiative transitions and strong decays of each state are also evaluated by applying our numerical wave functions. Comparing our results with the former results, we point out the difference among various models and derive new conclusions obtained in this paper. Our theoretical results are valuable for searching more $B_c$ mesons in experiments.
