Description

Seminário do Grupo de Física Teórica

Autora: Letícia Palhares - Departamento de Física Teórica - IF-UERJ

Título: Non-perturbative BRST breaking, confinement and Gribov copies

Resumo:  In this seminar, we investigate the role of a non-perturbative breaking of the BRST invariance in the infrared regime of non-Abelian gauge theories and its possible relation to confinement. This breaking naturally arises from the procedure of quantization of Landau-gauge Yang-Mills theories that takes into account the presence of Gribov copies. The resulting non-perturbative framework -- the Refined Gribov-Zwanziger theory -- is consistent with different lattice data. One can also construct direct signatures of BRST breaking in the matter sector of confining Yang-Mills theories that are in principle accessible via lattice simulations, allowing for a new non-perturbative model of matter confinement that can be treated (semi-)analytically.
