Semiclassical analysis of the phases of 4d SU(2) Higgs gauge systems with cutoff at the Gribov horizon

M. A. L. Capri, D. Dudal, A. J. Gomez +4

We present an analytical study of continuum 4d SU(2) gauge Higgs models with a single Higgs field with fixed length in either the fundamental or adjoint representation. We aim at a…

A study of the Higgs and confining phases in Euclidean SU(2) Yang-Mills theories in 3d by taking into account the Gribov horizon

M. A. L. Capri, D. Dudal, A. J. Gomez +3

We study SU(2) three-dimensional Yang-Mills theories in presence of Higgs fields in the light of the Gribov phenomenon. By restricting the domain of integration in the functional i…

Physical spectrum from confined excitations in a Yang-Mills-inspired toy model

M. A. L. Capri, D. Dudal, M. S. Guimaraes +2

We study a toy model for an interacting scalar field theory in which the fundamental excitations are confined in the sense of having unphysical, positivity-violating propagators, a…

The Gribov horizon and spontaneous BRST symmetry breaking

David Dudal, Silvio Paolo Sorella

An equivalent formulation of the Gribov-Zwanziger theory accounting for the gauge fixing ambiguity in the Landau gauge is presented. The resulting action is constrained by a Slavno…

Scalar-Tensor theories from Plebanski gravity

David Beke

We study a modification of the Plebanski action, which generically corresponds to a bi-metric theory of gravity, and identify a subclass which is equivalent to the Bergmann-Wagoner…

The No-Pole Condition in Landau gauge: Properties of the Gribov Ghost Form-Factor and a Constraint on the 2d Gluon Propagator

Attilio Cucchieri, David Dudal, Nele Vandersickel

We study the Landau-gauge Gribov ghost form-factor sigma(p^2) for SU(N) Yang-Mills theories in the d-dimensional case. We find a qualitatively different behavior for d=3,4 w.r.t. d…

The Gribov problem and QCD dynamics

N. Vandersickel, Daniel Zwanziger

In 1967, Faddeev and Popov were able to quantize the Yang-Mills theory by introducing new particles called ghost through the introduction of a gauge. Ever since, this quantization…
