2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/188612We develop a chiral SU(3) RMF model for octet baryons, as an extension of the recently developed chiral SU(2) RMF model with logarithmic sigma potential. For Sigma-meson coupling, strong repulsion(SR) and weak repulsion(WR) cases are examined in existing atomic shift data of Sigma^-. In both of these cases, we need an attractive pocket of a few MeV depth around nuclear surface.4 pages, 8 figures, to appear in the proceedings of the IX International Conference on Hypernuclear and Strange Particle Physics (HYP2006)Nuclear TheoryHypernuclei and nuclear matter in a chiral SU(3) RMF modeltext
