The strong coupling constant ghbBcPSBcV is calculated using the three-point QCD sum rules method. We use correlation functions to obtain these strong coupling constants with contributions of both BcPS and BcVmesons as off-shell states. The contributions of two gluon condensates as a radiative correction are considered. The results show that ghbBcPSBcV=8.80±2.84GeV−1and ghbBcVBcPS=9.34±3.12GeV−1 in the BcPS and BcV off-shell state, respectively.
