The refined Gribov-Zwanziger (RGZ) action in the Landau gauge provides a local and
renormalizable framework to account for the existence of infinitesimal Gribov copies in the …

We present a set of BRST invariant composite operators in the\(SU\left (2\right)\times U\left
(1\right)\) Higgs model which exhibit an overlap with the observable scalar and vector …

The refined Gribov-Zwanziger (RGZ) action in the Landau gauge accounts for the existence
of infinitesimal Gribov copies as well as the dynamical formation of condensates in the …

The spectral properties of a set of local gauge (BRST) invariant composite operators are
investigated in the SU (2) Yang–Mills–Higgs model with a single Higgs field in the …

We discuss the possibility to obtain a massive Landau gauge, based on the local composite
operator effective action framework combined with the Zimmermann reduction of couplings …

We introduce a background gauge akin to the Landau-DeWitt gauge but deformed by the
presence of a gauge parameter for the quantization of Euclidean Yang-Mills theories. In the …

A bstract The spectral properties of a set of local gauge-invariant composite operators are
investigated in the U (1) Higgs model quantized in the't Hooft R ξ gauge. These operators …

We consider a BRST-invariant generalization of the “massive background Landau gauge,”
resembling the original Curci-Ferrari model that saw a revived interest due to its …

We revisit the effective action of the Gribov–Zwanziger theory, taking into due account the
BRST symmetry and renormalization (group invariance) of the construction. We compute at …

We compute the one-loop quark-photon vertex and the quark magnetic moment in three
different models with an infrared-modified gluon propagator, namely: the massive (Curci …
