Gluon condensation and deconfinement critical density in nuclear matter
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 critical density,ρc turns out about nine times the saturation density, ρ0 for the value of the gluon condensate in vacuum < (αs/π)G 2 >= 0.012 GeV . For neutron matter ρc ≃ ...
متن کاملThe antikaon nuclear potential in hot and dense matter
The antikaon optical potential in hot and dense nuclear matter is studied within the framework of a coupled-channel self-consistent calculation taking, as bare meson-baryon interaction, the meson-exchange potential of the Jülich group. Typical conditions found in heavy-ion collisions at GSI are explored. As in the case of zero temperature, the angular momentum components larger than L = 0 contr...
متن کاملKaon Condensation in “Nuclear Star” Matter
The critical density for kaon condensation in “nuclear star” matter is computed up to two-loop order in medium (corresponding to next-to-next-to-leading order in chiral perturbation theory in free space) with a heavy-baryon effective chiral Lagrangian whose parameters are determined from KN scattering and kaonic atom data. To the order considered, the kaon self-energy has highly non-linear dens...
متن کاملDiquark Bose-Einstein Condensation and Nuclear Matter
We study a possible transition between symmetric nuclear matter and the diquark Bose-Einstein condensate (BEC) matter at zero temperature. We find that chiral restoration transition is first order and coincides with deconfinement. We investigate various possible coexistence patterns which may emerge from the first order deconfinement phase transition by assuming different values for the critica...
متن کاملRole of antikaon condensation in r-mode instability
We investigate the effect of antikaon condensed matter on bulk viscosity in rotating neutron stars. We use relativistic field theoretical models to construct the equation of state of neutron stars with the condensate, where the phase transition from nucleonic to K condensed phase is assumed to be of first order. We calculate the coefficient of bulk viscosity due to the non-leptonic weak interac...
