Spontaneous symmetry breaking as a mechanism for the Gribov scale in a BRST-invariant formulation
M. A. L. Capri, V. E. R. Lemes
We propose a BRST-invariant formulation of the Gribov--Zwanziger model in the Landau gauge, in which the Gribov scale is produced by the spontaneous breaking of a scalar quartet sy…
On Quasiparticles within the Refined Gribov-Zwanziger Model
Felipe F. Garcia, Marcio A. L. Capri, Bruno W. Mintz
The problem of the effective excitations of a gauge theory in the nonperturbative regime remains not completely understood. Using the Refined Gribov-Zwanziger (RGZ) theory as effec…
The supersymmetric extension of the replica model
M. A. L. Capri, R. C. Terin, H. C. Toledo
We perform a supersymmetric extension of the replica model quantized in the Landau gauge and compute the gluon and gluino propagators at tree-level, such results di…
An all order renormalizable Refined-Gribov-Zwanziger model with BRST invariant fermionic horizon function in linear covariant gauges
M. A. L. Capri, S. P. Sorella, R. C. Terin
We introduce, within the Refined-Gribov-Zwanziger setup, a composite BRST invariant fermionic operator coupled to the inverse of the Faddeev-Popov operator. As a result, an effecti…
Study of the renormalization of BRST invariant local composite operators in the Higgs model
M. A. L. Capri, I. F. Justo, L. F. Palhares +2
The renormalization properties of two local BRST invariant composite operators, , corresponding respectively to the gauge invariant description of the Higgs particle and o…
Covariant Mass and Geometrical setup in Euclidean gauge theories
A. R. de Sá, M. A. L. Capri, V. E. R. Lemes
A nonlocal mass operator can be consistently set in local form through the introduction of a set of additional fields with geometrical appropriated properties. A local and polynomi…
