Strong transitions of decuplet to octet baryons and pseudoscalar mesons

arXiv:1003.5467 · doi:10.1016/j.nuclphysa.2010.06.013

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.
