Abstract
The strong coupling constant is an important parameter that can help us understand the strong decay behaviors of baryons. In our previous work, we have analyzed the strong vertices [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] in QCD sum rules. Following these works, we further analyze the strong vertices [Formula: see text] and [Formula: see text] using the three-point QCD sum rules under Dirac structures [Formula: see text] and [Formula: see text]. In this work, we first calculate strong form-factors considering contributions of the perturbative part and the condensate terms [Formula: see text], [Formula: see text] and [Formula: see text]. Then, these form-factors are used to fit into analytical functions. According to these functions, we finally determine the values of the strong coupling constants for these two vertices [Formula: see text] and [Formula: see text].
