Chiral condensate in nuclear matter with vacuum corrections
arXiv:0805.1253 · doi:10.1142/S021773230802865X
Abstract
Within the relativistic Hartree approach using a Lagrangian with density-dependent parameters respecting the chiral limit, it is found that the vacuum corrections from the nucleon Dirac sea soften the equation of state and favor the chiral symmetry restoration at high densities.
