Cold, dense nuclear matter in a SU(2) parity doublet model
Cold, dense nuclear matter in a SU(2) parity doublet model
We study dense nuclear matter and the chiral phase transition in a SU(2) parity doublet model at zero temperature. The model is defined by adding the chiral partner of the nucleon, the N', to the linear sigma model, treating the mass of the N' as an unknown free parameter. The …
