Gluon condensation and deconfinement critical density in nuclear matter Original Research Article

An upper limit to the critical density for the transition to the deconfined phase, at zero temperature, has been evaluated by analyzing the behavior of the gluon condensate in nuclear matter. Due to the non-linear baryon density effects, the upper limit to the critical density, ρc turns out about nine times the saturation density, ρ0 for the value of the gluon condensate in vacuum 〈(αs/π)G2〉=0.012 GeV4. For neutron matter ρc≃8.5ρ0. The dependence of the critical density on the value of the gluon condensate in vacuum is studied.
