论文摘要
B $ _1 $ b $ _ {s0} $ k和b $ _1 $ _1 $ b $ _ {s1} $ k顶点的强耦合常数的改进计算在三点QCD总规则的框架中显示。当b $ _ {s0} $（b $ _ {s1} $）且k状态均为外壳时，计算耦合常数。考虑到$ su_f（3）$对称性，将结果与现有预测进行了比较。
An improved calculation of the strong coupling constants of B$_1$B$_{s0}$K and B$_1$B$_{s1}$K vertices is presented in the framework of the three-point QCD sum rules. The coupling constants are calculated, when both the B$_{s0}$(B$_{s1}$) and K states are off-shell. Considering the $SU_f(3)$ symmetry, the results are compared with the existing predictions.
