In recent years, the Gribov-Zwanziger action was refined by taking into account certain
dimension 2 condensates. In this fashion, one succeeded in bringing the gluon and the …

A definition of soft breaking of BRST symmetry in the field-antifield formalism is proposed,
valid for general gauge theories and arbitrary gauge fixing. The Ward identities for the …

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 …

We continue investigation of soft breaking of BRST symmetry in the Batalin–Vilkovisky (BV)
formalism beyond regularizations like dimensional ones used in our previous paper [JHEP …

We continue our research 1–4 and extend the class of finite BRST–anti-BRST
transformations with odd-valued parameters λ a, a= 1, 2, introduced in these works. In doing …

A consistent quantum treatment of general gauge theories with an arbitrary gauge-fixing in
the presence of soft breaking of the BRST symmetry in the field–antifield formalism is …

Some time ago, we introduced a route to provide confinement in the sense that particle
excitations would appear from condensates of fields that do not have physical asymptotic …

We study the ultraviolet properties of theories whose fundamental fields display a confining,
Gribov-type, propagator. These are propagators that exhibit complex poles and violate …

In this note, we consider the Landau gauge in the continuum formulation. Our purposes are
twofold. Firstly, we try to work out the consequences of the recently derived Cucchieri …

Inspired by the construction of the Gribov–Zwanziger action in the Landau gauge, we
introduce a quark model exhibiting both confinement and chiral symmetry aspects. An …
