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 …

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 propose a Gribov-Zwanziger type model action for the Landau-DeWitt gauge that
preserves, for any gauge group, the invariance under background gauge transformations. At …

The Landau background gauge, also known as the Landau–DeWitt gauge, has found
renewed interest during the past decade given its usefulness in accessing the confinement …

The topological susceptibility, χ 4, following the work of Witten and Veneziano, plays a key
role in identifying the relative magnitude of the η′ mass, the so-called U (1) A problem. A …

A joint introduction of composite and background fields into non-Abelian quantum gauge
theories is suggested based on the symmetries of the generating functional of Green's …

Non-Abelian gauge theories with composite fields are examined in the background field
method. Generating functionals of Green's functions for a Yang–Mills theory with composite …

In this work we investigate the effects of the Gribov prescription to get rid of zero-modes of
the Faddeev-Popov operator at a one-loop order in perturbation theory in the Landau-DeWitt …

Singularity of the gauge condition n⋅∂ n⋅ A= 0 at n⋅ k= 0 is studied here. Such singularity
is different from that in axial gauge and can not be regularized through analytical …
