Abstract：
In this article, we study the strong interaction of the vertices ∑_bNB and ∑_cND using the three-point QCD sum rules under two different Dirac structures. Considering the contributions of the vacuum condensates up to dimension 5 in the operation product expansion, the form factors of these vertices are calculated. Then, we fit the form factors into analytical functions and extrapolate them into time-like regions, which gives the coupling constants. Our analysis indicates that the coupling constants for these two vertices are G_{∑_bNB}=0.43±0.01 GeV^-1 and G_{∑_cND}=3.76±0.05 GeV^-1.
