Lorentz invariance violation in the extragalactic propagation of ultra-high energy photons and in the development of showers in the Earth crust and atmosphere
Denise Boncioli, Valdir Barbosa Bezerra, Matteo Giammarco +3
We investigate the effects of Lorentz invariance violation (LIV) on photon interactions, considering both intergalactic propagation (Breit-Wheeler process) and atmospheric interact…

Gravitational signatures of a nonlinear electrodynamics in gravity
A. A. Araújo Filho, N. Heidari, I. P. Lobo +1
In this work, we investigate a nonlinear electrodynamics model within the framework of gravity. We begin by outlining the general features of the theory and analyzing the…
