A refinement of the Gribov-Zwanziger approach in the Landau gauge: infrared propagators in harmony with the lattice results
David Dudal, John Gracey, Silvio Paolo Sorella +2
Recent lattice data have reported an infrared suppressed, positivity violating gluon propagator which is nonvanishing at zero momentum and a ghost propagator which is no longer enh…
Resolving the instability of the Savvidy vacuum by dynamical gluon mass
David Vercauteren, Henri Verschelde
In this paper we apply the formalism of local composite operators as developed by Verschelde et al. in combination with a constant chromomagnetic field as considered in the seventi…
Gauge invariant nonlocal mass operator in YM theories
D. Dudal, N. Vandersickel, H. Verschelde +5
We briefly describe the construction of a renormalizable gauge model based on the nonlocal gauge invariant mass operator F1/D^2F. We also take a look at the unitarity of the result…
The Gribov-Zwanziger action in the presence of the gauge invariant, nonlocal mass operator in the Landau gauge
M. A. L. Capri, D. Dudal, V. E. R. Lemes +4
We prove that the nonlocal gauge invariant mass dimension two operator can be consistently added to the Gribov-Zwanziger action, which implements the res…
Unitarity analysis of a non-Abelian gauge invariant action with a mass
David Dudal, Nele Vandersickel, Henri Verschelde
In previous work done by us and coworkers, we have been able to construct a local, non-Abelian gauge invariant action with a mass parameter, based on the nonlocal gauge invariant m…
UV finiteness of 3D Yang-Mills theories with a regulating mass in the Landau gauge
D. Dudal, J. A. Gracey, R. F. Sobreiro +2
We prove that three-dimensional Yang-Mills theories in the Landau gauge supplemented with a infrared regulating, parity preserving mass term are ultraviolet finite to all orders. W…
