Abstract

An improved calculation of the strong coupling constants of B1_1Bs0_{s0}K and B1_1Bs1_{s1}K vertices is presented in the framework of the three-point QCD sum rules. The coupling constants are calculated, when both the Bs0_{s0}(Bs1_{s1}) and K states are off-shell. Considering the SUf(3)SU_f(3) symmetry, the results are compared with the existing predictions.
