R(DD2YDelta) 1.1-1.1 (no electrons)
Abstract
This hadronic EOS table accounts for hyperons and ∆(1232) resonances in addition to nucleons [R_2022,ROS_2020]. The nucleonic RMF effective interaction is DD2 [TRKB_2010]. The coupling constants of exotic species to different mesonic fields are provided in the datasheet. For the clusterized phase occurring at sub-saturation densities we use data in HS(DD2) available on CompOSE; they have been obtained within a statistical model with excluded volume and interactions [HSNP_2010]. The transition from inhomogeneous matter to homogeneous matter is done by minimizing the free energy density. For the masses of nuclei, FRDM [MNKA_1997] was used.
