Title: The strong coupling constants of pseudoscalar mesons with decuplet--octet baryons in QCD
Abstract: The strong coupling constants of light pseudoscalar π, K and η mesons with decuplet–octet baryons are studied within light cone QCD sum rules, where SU(3)f symmetry breaking effects are taken into account. It is obtained that all coupling constants under the consideration are described by only one universal function even if SU(3)f symmetry breaking effects are switched into the game.
