Abstract

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.
