Title: Quark model study of strange dibaryon resonances

Abstract

Two nonrelativistic quark models, a chiral quark model and a quark delocalization color screening model, are employed to calculate the baryon-baryon scattering phase shifts to look for dibaryon resonances with strangeness by means of the resonating group method. The two models predict similar-strangeness dibaryon resonance states. No resonance appears in the octet-octet channels, but resonance did exist in the octet-decuplet and decuplet-decuplet channels. These resonances were distributed in the energy region 2400-2800 MeV. The widths are generally smaller than 10 MeV but increased to tens of MeV after taking into account the off-shell widths of decuplet baryons. These resonances all appear in the D-wave nucleon-hyperon and hyperon-hyperon scatterings and can be searched for through hyperon-nucleon scatterings with hyperon beams and hyperon-hyperon vertex and masses reconstruction with the data collected by relativistic heavy ion collisions.
