论文摘要
$ b_c $梅森的标准模型衰减速率与一种基于实验数据的使用与操作员产品扩展相结合的新方法进行了讨论。在新的方法差异中，考虑了$ b，\，d $和$ b_c $梅森衰减率的差异，为此，自由夸克的贡献退出，从而减少了理论预测。
The Standard Model decay rate of the $B_c$ meson is discussed together with a novel approach based on the usage of experimental data in combination with an operator product expansion. In the new method differences of $B,\,D$ and $B_c$ meson decay rates are considered, for which the free-quark contributions drop out, leading to a reduction of the theory prediction.
