Updating QCD2
(1996-02-01)
We review two-dimensional QCD. We start with the field theory aspects since 't Hooft's 1/N expansion, arriving at the non-Abelian bosonization formula, coset construction and gauge-fixing procedure. Then we consider the ...

Nambu–Jona-Lasinio SU(3) model constrained by lattice QCD: thermomagnetic effects in the magnetization
(2021-09-01)
We use a three-flavor Nambu–Jona-Lasinio model to study the thermodynamics of strange quark matter under a strong magnetic field. The model Lagrangian features flavor SU(3) four-quark interactions and six-quark interactions ...
Importance of asymptotic freedom for the pseudocritical temperature in magnetized quark matter
(2014-08-11)
Although asymptotic freedom is an essential feature of QCD, it is absent in effective chiral quark models like the Nambu-Jona-Lasinio and linear sigma models. In this work we advocate that asymptotic freedom plays a key ...
Coulomb gauge quark model, vacuum condensates and high density quark matter
(American Institute of Physics (AIP), 2002-01-01)
We consider here a Coulomb gauge quark model which includes an explicit construct for a nontrivial vacuum structure in QCD at finite density. Non-perturbative renormalization of ultraviolet diverges is performed by adding ...
Noise and ultraviolet divergences in the dynamics of the chiral condensate in QCD
(Iop Publishing Ltd, 2012-01-01)
The time evolution of the matter produced in high energy heavy-ion collisions seems to be well described by relativistic viscous hydrodynamics. In addition to the hydrodynamic degrees of freedom related to energy-momentum ...
Quark condensates and high density quark matter
(World Scientific Publ Co Pte Ltd, 2003-01-01)
We consider a Coulomb gauge quark model which includes an explicit construct for a nontrivial vacuum structure in QCD. The dynamics is described by a Hamiltonain that contains a linearly rising confining potential and ...
Superconducting quark matter in the Chromodielectric Model
(2004-12-02)
In this work we study the strange quark matter in an extented version of the Chromodielectric Model (CDM) with a BCS quark pairing implemented, and analyze the superconducting color flavor locked (CFL) phase. We compare ...
