Effect of in-medium hadron parameter modification on nuclear matter equation of state - art. no. 018202

We investigate the effect on the nuclear matter equation of state (EOS) due to modification of meson and nucleon parameters in a nuclear medium as a c onsequence of the partial restoration of chiral symmetry. To get the EOS, w e have used Brueckner-Bethe-Goldstone formalism with Bonn-B potential as a two-body interaction and QCD sum rule and Brown-Rho scaling prescriptions f or modification of hadron parameters. We find that the EOS is very much sen sitive to the meson parameters. We can fit, with the two-body interaction a lone, both the saturation density and the binding energy per nucleon.
