论文摘要
三个独家衰减的理论分析，$ b_ {c} \ to j/ψ+\ mathcal {r}，$，其中$ \ mathcal {r} = k+4π，$ 4 kk+3π$或$7π$。使用分解方法和共振近似（被证明在对其他类似衰减的分析中非常有用），我们在某些有趣的质量组合上获得了所需幅度并创建分布的分析表达式。提出的结果可用于与即将到来的实验数据进行比较，并更好地了解重夸克尼亚的性质。
Theoretical analysis of three exclusive decays, $B_{c}\to J/ψ+\mathcal{R},$where $\mathcal{R}=K+4π,$$KK+3π$, or $7π$, is given. Using the factorization method and the resonance approximation (methods proved to be very useful in the analysis of some other similar decays), we have obtained analytical expressions of the required amplitudes and created distributions over some interesting mass combinations. Presented results could be used for comparison with forthcoming experimental data and better understanding of the nature of heavy quarkonia.
