CONNECTION BETWEEN THE NUCLEAR-MATTER MEAN-FIELD EQUATION OF STATE AND THE QUARK AND GLUON CONDENSATES AT HIGH-DENSITY

It is known now that chiral symmetry restoration requires the meson-nu cleon couplings to be density-dependent in nuclear-matter mean-field m odels. We further show that, quite generally, the quark and gluon cond ensates in medium are related to the trace of the energy-momentum tens or of nuclear matter and in these models the incompressibility K must be less than 3 times the chemical potential mu. In the critical densit y rho(c), the gluon condensate is only reduced by 20%, indicating a la rger effective nucleon mass.
