Non-perturbative aspects of Euclidean Yang-Mills theories in linear covariant gauges: Nielsen identities and a BRST invariant two-point correlation function
M. A. L. Capri, D. Dudal, A. D. Pereira +5
In order to construct a gauge invariant two-point function in a Yang-Mills theory, we propose the use of the all-order gauge invariant transverse configurations A^h. Such configura…
On the gauge-invariant operator in Euclidean Yang-Mills theories
M. A. L. Capri, D. Fiorentini, M. S. Guimaraes +3
We review our recent work on the gauge-invariant non-local dimension-two operator , whose minimization is defined along the gauge orbit. Albeit non-local, the operat…
Aspects of the refined Gribov-Zwanziger action in linear covariant gauges
M. A. L. Capri, D. Fiorentini, A. D. Pereira +3
We prove the renormalizability to all orders of a refined Gribov-Zwanziger type action in linear covariant gauges in four-dimensional Euclidean space. In this model, the Gribov cop…
A local and renormalizable framework for the gauge-invariant operator in Euclidean Yang-Mills theories in linear covariant gauges
M. A. L. Capri, D. Fiorentini, M. S. Guimaraes +3
We address the issue of the renormalizability of the gauge-invariant non-local dimension-two operator , whose minimization is defined along the gauge orbit. Despite…
A local and BRST-invariant Yang-Mills theory within the Gribov horizon
M. A. L. Capri, D. Dudal, D. Fiorentini +7
We present a local setup for the recently introduced BRST-invariant formulation of Yang-Mills theories for linear covariant gauges that takes into account the existence of gauge co…
About the triviality of the higher derivative sector in the abelian Lee-Wick model
D. Fiorentini, V. J. Vasquez Otoya
Canonical quantization is reviewed here for the Abelian Lee-Wick model by using the Dirac constraints method, a Gupta-Bleuler-like prescription is implemented and the BRST charge o…
