THERMOSTATIC PROPERTIES OF NUCLEAR MATTER IN A SATURATING CHIRAL BREAKING FIELD THEORY

The saturating chiral breaking field theory are used to study thermostatic properties of nuclear matter for different regions of temperature in the framework of mean-field theory.The results given by Chowdhury et al.are improved and developed.By using the numerical integration for the Fermi integral,we find the low temperature approximation taken by Chowdhury et al.to be valid only when βμ_eff>2.4.The critical temperature T_c for the liquid-gas phase transition is obtained to be about 23MeV and the phase transition of the nucleon-antinucleon plasma is found in the range from T=150MeV to T=200MeV.
