Remarks on confinement driven by axion-like particles in Yang–Mills theories
- Physics
- 2008
Features of screening and confinement are studied for a non-Abelian gauge theory with a mixture of pseudoscalar and scalar couplings, in the case where a constant chromoelectric, or chromomagnetic,…
Indirect lattice evidence for the refined Gribov-Zwanziger formalism and the gluon condensate in the Landau gauge
- Physics
- 2010
We consider the gluon propagator D(p{sup 2}) at various lattice sizes and spacings in the case of pure SU(3) Yang-Mills gauge theories using the Landau gauge fixing. We discuss a class of fits in the…
Magnetic field and curvature effects on pair production. II. Vectors and implications for chromodynamics
- PhysicsPhysical Review D
- 2019
We calculate the pair production rates for spin-$1$ or vector particles on spaces of the form $M \times {\mathbb R}^{1,1}$ with $M$ corresponding to ${\mathbb R}^2$ (flat), $S^2$ (positive curvature)…
Electric and magnetic screenings of gluons in a model with a dimension-2 gluon condensate
- Physics
- 2011
Electric and magnetic screenings of thermal gluons are studied using the background expansion method in a gluodynamic model with a gauge invariant dimension-2 gluon condensate at zero momentum. At…

Monopole Condensation and Confinement of Color in SU(2) QCD
- Physics
- 2002
We resolve the controversy on the stability of the monopole condensation in the one-loop effective action of SU(2) QCD by calculating the imaginary part of the effective action with two different…
Gauge-invariant gluon mass, infrared Abelian dominance and stability of magnetic vacuum
- Physics
- 2006
We give an argument for deriving analytically the infrared “Abelian” dominance in a gauge invariant way for the Wilson loop average in SU(2) Yang– Mills theory. In other words, we propose a possible…
Non-perturbative calculation of the mass-gap in the Gross-Neveu model
- Physics
- 1997
We calculate a fully renormalizable effective action for local composite operators in the U(N) Gross-Neveu model, recently introduced by one of us, to two loop order. We obtain results for the…
Restricted gauge theory
- Physics
- 1980
A restricted gauge theory is obtained as a self-consistent subset of a non-Abelian gauge theory by imposing an extra magnetic symmetry to the gauge symmetry. The theory describes the dual dynamics…
