Kaon 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...

1. Introduction The Equation of State (EOS) of nuclear matter plays a fundamental role in the understanding of many aspects of nuclear physics and astrophysics. Transient states of nuclear matter far from normal conditions can be created in terrestrial laboratories and many experimental and theoretical efforts have been devoted to the study of nuclear reactions, from low to intermediate energie...
متن کاملGluon 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 کاملChiral Dynamics and Nuclear Matter
We calculate the equation of state of isospin-symmetric nuclear matter in the threeloop approximation of chiral perturbation theory. The contributions to the energy per particle Ē(kf ) from oneand two-pion exchange diagrams are ordered in powers of the Fermi momentum kf (modulo functions of kf/mπ). It is demonstrated that, already at orderO(k4 f ), two-pion exchange produces realistic nuclear b...
