The asymmetry of the dimension two condensate
David Vercauteren, David Dudal, John Gracey +2
I present recent analytical work concerning the electric-magnetic asymmetry in the dimension two condensate <A^2> in pure Yang-Mills theory. We reproduce qualitatively the lattice…
Analytic approach to the study of the electric-magnetic asymmetry of the dimension 2 condensate
David Vercauteren, David Dudal, John Gracey +2
Recent work by Chernodub and Ilgenfritz has uncovered non-trivial temperature dependence in the electric-magnetic asymmetry in the dimension 2 condensate. This asymmetry measures t…
From propagators to glueballs in the Gribov-Zwanziger framework
N. Vandersickel, D. Dudal, O. Oliveira +1
Over the last years, lattice calculations in pure Yang-Mills gauge theory seem to have come more or less to a consensus. The ghost propagator is not enhanced and the gluon propagat…
On the reanimation of a local BRST invariance in the (Refined) Gribov-Zwanziger formalism
D. Dudal, N. Vandersickel
We localize a previously established nonlocal BRST invariance of the Gribov-Zwanziger (GZ) action by the introduction of additional fields. We obtain a modified GZ action with a co…
Glueball masses from an infrared moment problem and nonperturbative Landau gauge
D. Dudal, M. S. Guimaraes, S. P. Sorella
We set up an infrared-based moment problem to obtain estimates of the masses of the scalar, pseudoscalar and tensor glueballs in Euclidean Yang-Mills theories using the Refined Gri…
From unphysical gluon and ghost propagators to physical glueball propagators (in the Gribov-Zwanziger picture): a not so trivial task?
D. Dudal, N. Vandersickel, L. Baulieu +5
During recent years, a good agreement was found between the analytical derivation and the numerical simulation of the Landau gauge gluon and ghost propagators. We mention the Schwi…
Gribov horizon and BRST symmetry: a pathway to confinement
S. P. Sorella, L. Baulieu, D. Dudal +4
We summarize the construction of the Gribov-Zwanziger action and how it leads to a scenario which explains the confinement of gluons, in the sense that the elementary gluon excitat…
More on the renormalization of the horizon function of the Gribov-Zwanziger action and the Kugo-Ojima Green function(s)
D. Dudal, S. P. Sorella, N. Vandersickel
In this paper we provide strong evidence that there is no ambiguity in the choice of the horizon function underlying the Gribov-Zwanziger action. We show that there is only one cor…
