Nuclear equation of state with finite-range effective interactions

The equation of state of nuclear matter has been studied by using finite-ra nge phenomenological effective interactions having Gaussian and Yukawa func tional form. The single-particle momentum distribution function has been ev aluated self-consistently to obtain the single-particle energy energy densi ty and chemical potential at a thermal equilibrium. By using this self-cons istent procedure the free-energy density, pressure, entropy density, effect ive mass and incompressibility of nuclear matter have also been calculated. The possible temperature, momentum and density dependence of these quantit ies, particularly the mean field, effective mass and incompressibility, hav e been discussed. The phase transition to quark-gluon plasma has been studi ed for a zeroth-order bag model expression of quark pressure. The influence of the functional form of the effective interaction on these studies has a lso been discussed.
