g DsDK*0 and g BsDK*0 coupling constants in QCD sum rules

Abstract

In the present study, we calculate the strong coupling constants g DsDK* 0(800) and g BsDK* 0(800) within the three-point QCD sum rules approach. We evaluate the correlation function of the considered vertices taking into account both D[B] and K* 0(800) mesons as off-shell states.
