gD(s)DK(0)(*) and gB(s)DK(0)(*) coupling constants in QCD sum rules

2012    Sahin, S.; Sundu, H.; Azizi, K.

In the present study, we calculate the strong coupling constants gD(s)DK(0)(*)(800) and gB(s)BK(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 offshell states.
