S. Gao et al., TEMPERATURE AND DENSITY EFFECTS ON NUCLEON-NUCLEON INTERACTION FOR CHIRAL SIGMA-OMEGA MODEL, Nuclear physics. A, 593(3), 1995, pp. 362-376
In the framework of thermo field dynamics, the temperature and density
effects on nucleon-nucleon interaction for the chiral sigma-omega mod
el are investigated. The effective masses of the nucleon, pion, sigma
meson and omega meson and the vertex corrections at finite-temperature
and density are calculated. We have found that the potential well of
the nucleon-nucleon interaction becomes shallow as the density increas
es.
