Confined but chirally and chiral spin symmetric hot matter
L. Ya. Glozman, A. V. Nefediev, R. F. Wagenbrunn
We investigate properties of the quark--antiquark mesons at zero and finite temperature in the framework of a solvable chirally symmetric quark model with linear confining potentia…
Chiral symmetry restoration at finite temperature in a model with manifest confinement
L. Ya. Glozman, A. V. Nefediev, R. Wagenbrunn
Multiple lattice evidences support the existence of a confining but chirally symmetric regime of QCD above the chiral symmetry restoration crossover at Tch ~ 155 MeV. This regime i…
Effective Chiral Symmetry Restoration for Heavy-Light Mesons
V. K. Sazonov, G. Schaffernak, R. F. Wagenbrunn
We study the spectrum of heavy-light mesons within a model with linear instantaneous confining potential. The single-quark Green function and spontaneous breaking of chiral symmetr…
Chiral restoration phase transition within the quarkyonic matter
L. Ya. Glozman, V. K. Sazonov, R. F. Wagenbrunn
We overview a possible mechanism for confining but chirally symmetric matter at low temperatures and large densities. As a new development we employ a diffused quark Fermi surface…
Chirally symmetric and confining dense matter with a diffused quark Fermi surface
L. Ya. Glozman, V. K. Sazonov, R. F. Wagenbrunn
It is possible that at low temperatures and large density there exists a confining matter with restored chiral symmetry, just after the dense nuclear matter with broken chiral symm…
Axial charges of octet and decuplet baryons

The axial charges of the nucleon and the well-established N* resonances are studied within a consistent framework. For the first time the axial charges of the N* resonances are pro…
Second order chiral restoration phase transition at low temperatures in quarkyonic matter
L. Ya. Glozman, R. F. Wagenbrunn
In this Addendum to our recent paper, Phys. Rev. D 77, 054027 (2008), we point out that a chiral restoration phase transition in a quarkyonic matter at low temperatures is of secon…
Chirally symmetric but confined hadrons at finite density
L. Ya. Glozman, R. F. Wagenbrunn
At a critical finite chemical potential and low temperature QCD undergoes the chiral restoration phase transition. The folklore tradition is that simultaneously hadrons are deconfi…
Chirally symmetric but confining dense and cold matter
L. Ya. Glozman, R. F. Wagenbrunn
The folklore tradition about the QCD phase diagram is that at the chiral restoration phase transition at finite density hadrons are deconfined and there appears the quark matter. W…
Chiral symmetry patterns of excited mesons with the Coulomb-like linear confinement
R. F. Wagenbrunn, L. Ya. Glozman
The spectrum of mesons in a model where the only interaction is a linear Coulomb-like instantaneous confining potential is studied. The single-quark Green function as we…
Mesons and diquarks in Coulomb-gauge QCD
R. F. Wagenbrunn
I demonstrate how confinement in Coulomb-gauge QCD makes quark-quark states of the color anti-triplet (diquarks) move out of the physical spectrum. Mesons as color singlet quark-an…
Effective restoration of chiral symmetry in excited mesons
R. F. Wagenbrunn, L. Ya. Glozman
A fast restoration of chiral symmetry in excited mesons is demonstrated. A minimal "realistic" chirally symmetric confining model is used, where the only interaction between quarks…
