Abstract
The strong interaction between heavy and kaon mesons can consistently described by coupling constant in an effective lagrangian. Here, the improved strong coupling constants of gBs0B1K and gBs1B1K vertices in the framework of the three-point QCD sum rules are calculated. The coupling constants are calculated, when both the B1 and K states are off-shell. In this calculation, the contributions of the quark-quark, quark-gluon, and gluon-gluon condensates corrections are considered. By considering the SUf(3) symmetry, the comparison of results with existing predictions has also been made.
