Abstract

An improved calculation of the strong coupling constants of B₁B_s0K and B₁B_s1K 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.
