The Casimir effect in Gribov-Zwanziger theory
David Dudal, Philipe De Fabritiis, Sebbe Stouten +1
We consider Yang-Mills theory with two infinite parallel plates, separated by a distance \(L\), that are perfect magnetic conductors (PMC) or perfect electric conductors (PEC). Rec…
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…
Numerical approach to the Bell-Clauser-Horne-Shimony-Holt inequality in quantum field theory
Philipe De Fabritiis, Marcelo S. Guimaraes, Itzhak Roditi +1
The Bell-CHSH (Clauser-Horne-Shimony-Holt) inequality in the vacuum state of a relativistic scalar quantum field is analyzed. Using Weyl operators built with smeared fields localiz…
Four-gluon vertex from the Curci-Ferrari model at one-loop order
Nahuel Barrios, Philipe De Fabritiis, Marcela Peláez
We compute the four-gluon vertex from the Curci-Ferrari model at one-loop order for a collinear configuration. Our results display a good agreement with the first lattice data for…
Using Weyl operators to study Mermin's inequalities in Quantum Field Theory
Philipe De Fabritiis, Fillipe M. Guedes, Marcelo S. Guimaraes +2
Mermin's inequalities are investigated in a Quantum Field Theory framework by using von Neumann algebras built with Weyl operators. We devise a general construction based on the To…

The violation of the Bell-CHSH inequality in the vacuum state of a relativistic free real scalar field is established by means of the Tomita-Takesaki construction and of the direct…
Maximal violation of the Bell-Clauser-Horne-Shimony-Holt inequality via bumpified Haar wavelets
David Dudal, Philipe De Fabritiis, Marcelo S. Guimaraes +2
We devise a general setup to investigate the violation of the Bell-CHSH inequality in the vacuum state in the context of Quantum Field Theory. We test the method with massless spin…
Probing Mermin's inequalities violations through pseudospin operators
Philipe De Fabritiis, Itzhak Roditi, Silvio P. Sorella
The violation of Mermin's inequalities is analyzed by making use of two different Bell setups built with pseudospin operators. Employing entangled states defined by means of squeez…
Entangled coherent states and violations of Bell-CHSH inequalities
Philipe De Fabritiis, Fillipe M. Guedes, Giovani Peruzzo +1
Three classes of entangled coherent states are employed to study the Bell-CHSH inequality. By using pseudospin operators in infinite dimensional Hilbert spaces, four dichotomic ope…
BRST invariant formulation of the Bell-CHSH inequality in gauge field theories
David Dudal, Philipe De Fabritiis, Marcelo S. Guimaraes +2
A study of the Bell-CHSH inequality in gauge field theories is presented. By using the Kugo-Ojima analysis of the BRST charge cohomology in Fock space, the Bell-CHSH inequality is…

Philipe De Fabritiis, Itzhak Roditi, Silvio Paolo Sorella
A relativistic Quantum Field Theory framework is devised for Mermin's inequalities. By employing smeared Dirac spinor fields, we are able to introduce unitary operators which creat…
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…

In this work we propose a parity-invariant Maxwell-Chern-Simons model coupled with two charged scalar fields in dimensions, and show that it admits finite-…
Phenomenology of a Born-Infeld extension of the sector at lepton colliders
P. De Fabritiis, P. C. Malta, J. A. Helayël-Neto
In this work we perform a non-linear extension of the sector of the Standard Model leading to novel quartic effective interactions between the neutral gauge bosons.…

P. De Fabritiis, P. C. Malta, M. J. Neves
We study CPT-odd non-minimal Lorentz-symmetry violating couplings in the electroweak sector modifying the interactions between leptons, gauge mediators and the Higgs boson. The tre…
