Analysis of the vertices rho NN, rho Sigma Sigma and rho Xi Xi with light-cone QCD sum rules

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.
