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 ...
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 ...
Improved statistical quark model for the nucleon structure function
(2010-08-26)
An improved statistical quark model, with quark energy levels given by a central linear confining potential, is used to obtain the light sea-quark asymmetry, d̄/ū, and also for the corresponding difference d̄-ū, inside the ...
Statistical quark models for the nucleon structure functions
(2010-12-01)
We consider some existing relativistic models for the nucleon structure functions, relying on statistical approaches instead of perturbative ones. These models are based on the Fermi-Dirac distribution for the confined ...
Statistical quark model for the nucleon structure function
(2009-11-27)
A statistical quark model, with quark energy levels given by a central linear confining potential is used to obtain the light sea-quark asymmetry, d̄/ū, and also for the ratio d/u, inside the nucleon. After adjusting a ...
Charmed-meson scattering on nucleons in a QCD Coulomb gauge quark model
(2007-03-01)
The scattering of charmed mesons on nucleons is investigated within a chiral quark model inspired on the QCD Hamiltonian in Coulomb gauge. The microscopic model incorporates a longitudinal Coulomb confining interaction ...
Limits on anomalous top quark gauge couplings from Tevatron and LHC data
(2015-01-01)
We review and update current limits on possible anomalous couplings of the top quark to W gauge bosons. We consider data from top quark decay (as encoded in the W-boson helicity fractions) and single-top production (in the ...
Heavy-light mesons scattering from nucleons: Quark-gluon and meson exchanges
(2010-12-01)
We investigate the scattering of heavy-light K and D mesons by nucleons at low energies. The short-distance part of the interaction is described by quark-gluon interchange and the longdistance part is described by a ...
Exploring Hot Quark Matter in Strong Magnetic Fields
(World Scientific Publ Co Pte Ltd, 2017-01-01)
Considering LQCD results for the quark condensates we determine the thermomagnetic dependence of NJL model coupling and then study the thermodynamical properties of hot magnetized quark matter.
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 ...
