Description
The coupling constants gD*(s) DK*(892) and gB*sBK*(892) are calculated in the framework of three-point QCD sum rules. The correlation functions responsible for these coupling constants are evaluated considering contributions of both D(B) and K*(892) mesons as off-shell states, but in the absence of radiative corrections. The results gD*sDK*(892) = (3.74 +/- 1.38) GeV-1 and gB*sBK*(892) = (3.24 +/- 1.08) GeV-1 are obtained for the considered strong coupling constants.
