Lorentz-symmetry violating physics in a supersymmetric scenario in -D
L. D. Bernal, Patricio Gaete, Y. P. M. Gomes +1
We study the dimensional reduction for a -dimensional Lorentz Violating Lagrangian in the matter and gauge sectors in a Supersymmetric scenario. We thus obtain an effective…
Limits on non-minimal Lorentz violating parameters through FCNC and LFV processes
Y. M. P. Gomes, J. A. Helayel-Neto
In this work we analyse a non-minimal Lorentz-violating extension of the electroweak theory in the fermionic sector. Firstly we analyse the relation between the CKM rotation in the…
Testing Lorentz-symmetry violation via electroweak decays
Y. M. P. Gomes, P. C. Malta, M. J. Neves
In this work we introduce CPT-odd non-minimal Lorentz-symmetry violating couplings to the electroweak sector modifying the interaction between leptons and gauge bosons. The vertex…
Elastic light-by-light scattering in a nonminimal Lorentz violation scenario
Y. M. P. Gomes, J. T. Guaitolini Junior
In the last years the Lorentz Violation scheme was implemented in QFT, in special in standard model of particle physics, in an attempt to explain our actual open problems. In this…
Fermionic Solutions of a Five-Dimensional Chern-Simons AdS Supergravity without Gravitino
Y. M. P. Gomes
Based on recent discussions on the so-called unconventional supersymmetry, we analyze a class of solutions of a 5D Chern-Simons AdS--SUGRA formulation without gravitin…
