Yang-Mills theories at finite temperature quantized in linear covariant gauges: gauge copies and semi-non-perturbative effects
Luigi Carvalho Ferreira
We consider four-dimensional Euclidean Yang-Mills theories quantized in the maximal Abelian and linear covariant gauges at finite temperature. Non-perturbatively, the Faddeev-Popov…
Infrared propagators of Yang-Mills-Chern-Simons theories in linear covariant gauges
Luigi C. Ferreira, Diego R. Granado, Igor F. Justo +1
Recent works have explored non-perturbative effects due to the existence of (infinitesimal) Gribov copies in Yang-Mills-Chern-Simons theories in three Euclidean dimensions. In part…
Hints of (de)confinement in Yang-Mills-Chern-Simons theories in the maximal Abelian gauge
Luigi C. Ferreira, Antonio D. Pereira, Rodrigo F. Sobreiro
The study of Yang-Mills theories in three dimensions is an insightful playground to grasp important features for the four-dimensional case. Additionally, in three dimensions, the C…
Momentum routing invariance in Feynman diagrams and quantum symmetry breakings
L. C. Ferreira, A. L. Cherchiglia, Brigitte Hiller +2
We illustrate with examples that quantum symmetry breakings in perturbation theory are connected to breakdown of momentum routing invariance (MRI) in the loops of a Feynman diagram…
Axial Vector Coupling and Chiral Anomaly in the Spectral Quark Model
L. C. Ferreira, A. L. Mota
We studied the Adler-Bardeen-Bell-Jackiw anomaly in the context of a finite chiral quark model known as the Spectral Quark Model. Within this model, we obtain the general non-local…
