Abstract

The strong coupling constant ghbBcPSBcV_{h_{b}B_{c}^{PS}B_{c}^{V}} 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_{c}^{PS} and BcV_{c}^{V}mesons as off-shell states. The contributions of two gluon condensates as a radiative correction are considered. The results show that ghbBcPSBcV=8.80±2.84GeV1_{h_{b}B_{c}^{PS}B_{c}^{V}}=8.80\pm 2.84 GeV^{-1}and ghbBcVBcPS=9.34±3.12GeV1_{h_{b}B_{c}^{V} B_{c}^{PS}}=9.34\pm 3.12 GeV^{-1} in the BcPSB_{c}^{PS} and BcVB_{c}^{V} off-shell state, respectively.
