Abstract: | We calculate saturation curves for strange hadron matter using recently constructed baryon-baryon potentials which are constrained by SU(3) symmetry. All possible interaction channels within the baryon octet (consisting of N,Λ,Σ, and Ξ) are considered. It is found that a small Λ fraction in nuclear matter slightly increases binding, but that larger fractions (>10%) rapidly cause a decrease. Charge-neutral {N,Λ,Ξ} systems, with equal densities for nucleons and cascades, are only very weakly bound. The dependence of the binding energies on the strangeness per baryon, fs, is predicted for various {N,Λ,Ξ} and {N,Λ,Σ,Ξ} systems. The implications of our results in relativistic heavy-ion collisions and the core of a dense star are discussed. We also discuss the differences between our results and previous hadron matter calculations. |
