Abstract

We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants entering the calculations can be expressed in terms of only one invariant function even if the SU(3)(f) symmetry breaking effects are taken into account. We estimate the order of SU(3)(f) symmetry violations, which are automatically considered by the employed approach.
