Abstract

In the extended chiral SU(3) quark model, we studied the structure of (Σ * Δ) S T = 0 5 2 dibaryon with strangeness s = − 1. Our research mainly focuses on three aspects: the contribution of vector mesons, the influence of the hidden-color channel (CC), and the stability of the system under the color screening effect. We found that the (Σ * Δ) S T = 0 5 2 can form a bound dibaryon with a broad width. In the short-range interaction, the repulsive effect provided by vector ρ , ω fields is quite similar to one-gluon-exchange (OGE) in the chiral SU(3) quark model. The CC effect promotes the formation of (Σ * Δ) S T = 0 5 2 bound state. The binding properties are stable when different confining potentials are considered. [ABSTRACT FROM AUTHOR]
