Hypernuclei and nuclear matter in a chiral SU(3) RMF model

概要

• 論文の詳細を見る

• We 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 Σ -meson coupling, strong repulsion (SR) and weak repulsion (WR) cases are examined in existing atomic shift data of Σ- . In both of these cases, we need an attractive pocket of a few MeV depth around nuclear surface.
