Quark condensate and chiral symmetry restoration in neutron stars
نویسندگان
چکیده
Based on an equivparticle model, we investigate the in-medium quark condensate in neutron stars. Carrying out a Taylor expansion of nuclear binding energy to order $\rho^3$, obtain series EOSs for star matter, which are confronted with latest and astrophysical constraints. The is then extracted from constrained properties decreases non-linearly density. However, chiral symmetry only partially restored non-vanishing condensates, may vanish at density that reach

Light quark masses, chiral condensate and quark-gluon condensate in quenched lattice QCD with exact chiral symmetry
We determine several quantities in quenched lattice QCD with exact chiral symmetry. For 100 gauge configurations generated with Wilson gauge action at β = 6.0 on the 163 × 32 lattice, we compute quenched quark propagators for 13 bare quark masses. The pion decay constant is extracted from the pion propagator, and from which the inverse lattice spacing is determined to be a−1 = 1.979(6) GeV. The...
متن کاملChiral Lagrangians and quark condensate in nuclei
We study the evolution with density of the quark condensate in the nuclear medium with interacting nucleons and including the short range correlations. We work with two chiral models, the linear sigma model and the non-linear one. For the last one we use two versions, one which does not satisfy PCAC, and another one which does. We show that the quark condensate, as other observables, is indepen...
متن کاملQuark matter in neutron stars
According to quantum chromodynamics, matter at ultra-high density and low temperature is a quark liquid, with a condensate of Cooper pairs of quarks near the Fermi surface (“color superconductivity”). This paper reviews the physics of color superconductivity, and discusses some of the proposed signatures by which we might detect quark matter in neutron stars.
متن کاملChiral Symmetry and Quark Connnement
In the physical vacuum of QCD, the energy density of light-quark elds strongly coupled to slowly varying gluon elds can be negative, and so a condensate of pairs of quarks and antiquarks of nearly opposite momenta forms which breaks chiral symmetry, connnes quarks, and makes gluons massive.
متن کاملChiral Symmetry Restoration in Hadron
The evidence and the theoretical justification of chiral symmetry restoration in high-lying hadrons is presented. I. CHIRAL SYMMETRY RESTORATION OF THE SECOND KIND It has recently been suggested that the parity doublet structure seen in the spectrum of highly excited baryons may be due to effective chiral symmetry restoration for these states [1]. This phenomenon can be understood in very gener...
