An effective model is used to study the equation of state(EOS) of warm strange hadronic matter with nucleons, Λ-hyperons, Ξ-hyperons, σ * and φ. In the calculation, a newest weak Y-Y interaction deduced from the recent observation[1] of a 6 ΛΛ He double hypernucleus is adopted. Employing this effective model, the results with strong Y-Y interaction and weak Y-Y interaction are compared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
