The coupling constants gDsββDKβ(892)β and
gBsββBKβ(892)β 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
Kβ(892) mesons as off-shell states, but in the absence of radiative
corrections. The results, gDsββDKβ(892)β=(4.31Β±1.42)GeVβ1 and gBsββBKβ(892)β=(3.24Β±1.08)GeVβ1 are
obtained for the considered strong coupling constants.Comment: 13 Pages and 11 Figure
