Özet
Taking into account the SU(3)(f) breaking effects, the strong coupling constants of the pi, K, and eta mesons with decuplet baryons are calculated within the light cone QCD sum rules method. It is shown that all coupling constants, even in the case of SU(3)(f) breaking, are described in terms of only one universal function. It is shown that for Xi(*0)->Xi(*0)eta, transition violation of SU(3)(f) symmetry is very large and for other channels when SU(3)(f) symmetry is violated, its maximum value constitutes 10%divided by 15%.
