A Supersymmetric Extension of Axionic Electrodynamics: From Axions and Photons to Axinos and Photinos
C. Roldán-Domínguez, H. Belich, W. Spalenza +3
In this contribution, we investigate a supersymmetric effective extension of Axionic Electrody- namics by adopting the superspace/superfield approach. Rather than focusing on UV-co…
Black hole lensing in Kerr-de Sitter spacetimes
Eunice Omwoyo, Humberto Belich, Júlio C. Fabris +1
We have derived analytical solutions using Jacobi elliptic functions for bound and nearly bound photon orbits in Kerr-de Sitter (KdS) and Kerr-de Sitter Revisited (RKdS) spacetimes…
Aspects of the gauge boson-gaugino mixing in a supersymmetric scenario with Lorentz-symmetry violation
R. C. Terin, W. Spalenza, H. Belich +1
We write down an supersymmetric extension for non-Abelian gauge theories in (1+3) dimensions with a Lorentz- and CPT-violating term of the Carroll-Field-Jackiw type…
Remarks on the black hole shadows in Kerr-de Sitter space times
Eunice Omwoyo, Humberto Belich, Júlio C. Fabris +1
This work is geared towards analysis of shadows cast by Kerr-de Sitter (KdS) and Kerr-de Sitter Revisited (RKdS) black holes. Considering observers in the vicinity of the static ra…
Effects of a Landau-type quantization induced by the Lorentz symmetry violation on a Dirac field
R. L. L. Vitória, H Belich
Inspired by the extension of the Standard Model, we analyzed the effects of the spacetime anisotropies on a massive Dirac field through a non-minimal CPT-odd coupling in the Dirac…
Relativistic quantum oscillators in the global monopole spacetime
E. A. F. Bragança, R. L. L. Vitória, H. Belich +1
We investigated the effects of the global monopole spacetime on the Dirac and Klein-Gordon relativistic quantum oscillators. In order to do this, we solve the Dirac and Klein-Gordo…
