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…

Gravitational Compton scattering at zero and finite temperature
L. A. S. Evangelista, A. F. Santos
The Lagrangian formulation of Gravitoelectromagnetism (GEM) theory is considered. GEM is a gravitational theory constructed based on the similarities between gravity and electromag…

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…
