Abstract:Last year, the Ξ(1620) state that is cataloged in the Particle Data Group (PDG) with only one star is reported again in the Ξ − π + final state by the Belle Collaboration. Its properties not only the spectroscopy but also the decay width cannot be simply explained in the context of conventional constituent quark models. This intrigues an active discussion on the structure of this resonance. In this work, we study the radiative decays of the newly observed Ξ(1620) assuming that it is a meson-baryon molecular st… Show more
