Non-linear electrodynamics emerging from a Lorentz-symmetry violation scenario
M. J. Neves, G. Peruzzo
The effective action at one-loop for the quantum electrodynamics (QED) in the presence of background vectors and tensors that break the Lorentz symmetry is calculated in this work.…
Local gauge-invariant vector operators in the adjoint Higgs model
Giovani Peruzzo
In this work, we scrutinize local gauge-invariant vector operators of dimension four in the adjoint Higgs model, which are candidates for interpolating fields of the fundam…
Useful trick to compute correlation functions of composite operators
Giovani Peruzzo
In general, in gauge field theories, physical observables are represented by gauge-invariant composite operators, such as the electromagnetic current. As we recently demonstrated i…
Gauge-invariant scalar and vector operators in the Higgs model: Ward identities and renormalization
Giovani Peruzzo
In this work, we investigate the renormalization of the gauge-invariant composite operators proposed in \cite{Dudal:2023jsu} to describe the Higgs model from a g…
Weyl operators, Tomita-Takesaki theory, and Bell-Clauser-Horne-Shimony-Holt inequality violations
P. De Fabritiis, F. M. Guedes, M. S. Guimaraes +3
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…
BRST invariant scalar and vector operators in the Higgs model
David Dudal, Duifje Maria van Egmond, Giovani Peruzzo +1
We present a set of BRST invariant composite operators in the Higgs model which exhibit an overlap with the observable scalar and vector pa…
