Pion Effect of Nuclear Matter in a Chiral Sigma Model
Authors:HU Jin-niu  Y.Ogawa  H.Toki  A.Hosaka  SHEN Hong
Abstract:We develop a new framework for the study of the nuclear matter based on the linear sigma model.We introduce a completely new viewpoint on the treatment of the nuclear matter with the inclusion of the pion.We extend the relativistic chiral mean field model by using the similar method in the tensor optimized shell model.We also regulate the pion-nucleon interaction by considering the form-factor and short range repulsion effects.We obtain the equation of state of nuclear matter and study the importance of the pion effect.
Keywords:extended relativistic mean field model  chiral symmetry  pion exchange
