Strong transitions of decuplet to octet baryons and pseudoscalar mesons

Abstract

The strong coupling constants of light pseudoscalar $\pi$, $K$ and $\eta$ 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.
