Charting the different phases of Yang-Mills-Chern-Simons-Higgs theories
Daniel O. R. Azevedo, Gustavo P. de Brito, Philipe De Fabritiis +1
We explore Yang-Mills-Chern-Simons theories coupled to a Higgs-like field in the fundamental representation of quantized in linear covariant gauges in three Euclidean dimen…
Infrared gluon propagator in the Refined Gribov-Zwanziger scenario at one-loop order in the Landau gauge
Gustavo P. de Brito, Antonio D. Pereira
The Refined Gribov-Zwanziger (RGZ) action in the Landau gauge provides a local and renormalizable framework to account for the existence of infinitesimal Gribov copies in the path…
Quadratic gravity in analogy to quantum chromodynamics: Light fermions in its landscape
Gustavo P. de Brito
We investigate a non-perturbative approach to quantum gravity built in terms of analogies between quadratic gravity and quantum chromodynamics. This approach is based on a conjectu…
Fate of chiral symmetry in Riemann-Cartan geometry
Gustavo P. de Brito, Antonio D. Pereira, Arthur F. Vieira
We study the mechanism of chiral symmetry breaking for fermionic systems in a gravitational background with curvature and torsion. The analysis is based on a scale-dependent effect…
On the weak-gravity bound for a shift-symmetric scalar field
Gustavo P. de Brito, Benjamin Knorr, Marc Schiffer
The weak-gravity bound has been discovered in several asymptotically safe gravity-matter systems. It limits the strength of gravitational fluctuations that are compatible with an u…
Refined Gribov-Zwanziger theory coupled to scalar fields in the Landau gauge
Gustavo P. de Brito, Philipe De Fabritiis, Antonio D. Pereira
The Refined Gribov-Zwanziger (RGZ) action in the Landau gauge accounts for the existence of infinitesimal Gribov copies as well as the dynamical formation of condensates in the inf…
