The Hidden Symmetries of Yang-Mills Theory in (1+1)-dimensions
L. A. Ferreira, G. Luchini, H. Malavazzi
We present an integral formulation of classical Yang-Mills theory coupled to fermionic and scalar matter fields in (1+1)-dimensional Minkowski spacetime. By reformulating the local…
Thermal and Casimir effects in a Lorentz-violating massive scalar field
D. S. Cabral, L. H. A. R. Ferreira, L. A. S. Evangelista +1
In this work, a massive scalar field theory incorporating Lorentz violation is investigated. The symmetry breaking is introduced via a background traceless antisymmetric tensor. Wi…
Electron-positron scattering at finite temperature in Podolsky electrodynamics
D. S. Cabral, L. A. S. Evangelista, L. H. A. R. Ferreira +1
The electron-positron annihilation process is investigated within the framework of Podolsky's generalized electrodynamics at finite temperature. In this theory, a higher-derivative…
Lorentz-violating Yukawa theory at finite temperature
D. S. Cabral, L. A. S. Evangelista, J. C. R. de Souza +2
This paper addresses Yukawa theory, focusing on the scattering between two identical fermions mediated by an intermediate scalar boson, considering the effects of thermal contribut…
Scalar sector of the Myers and Pospelov model: thermal and size effects
L. H. A. R. Ferreira, A. F. Santos, Carlos M. Reyes
The scalar sector of the Myers and Pospelov model is considered. This theory introduces a dimension 5 operator with a preferred four-vector which breaks Lorentz symmetry. We invest…
