Description
In this article, we calculate the strong coupling constants of the ρNN, ρΣΣ, and ρΞΞ in the framework of the light-cone QCD sum rules approach. The strong coupling constants of the meson-baryon-baryon are the fundamental parameters in the one-boson exchange model which describes the baryon-baryon interactions successfully. The numerical values are in agreement with the existing calculations in part. The electric and magnetic F/(F+D) ratios deviate from the prediction of the vector meson dominance theory; the SU(3) symmetry breaking effects are very large
