Twisted Supersymmetry in a Deformed Wess-Zumino Model in (2+1) Dimensions
C. Palechor, A. F. Ferrari, A. G. Quinto
Non-anticommutative deformations have been studied in the context of supersymmetry (SUSY) in three and four space-time dimensions, and the general picture is that highly nontrivial…
Nonminimal Lorentz-Violating Effects in Photon Physics
Alysson Fabio Ferrari
We study an extension of QED involving a light pseudoscalar (an axion-like particle), together with a very massive fermion which has Lorentz-violating interactions with the photon…
The role of singular spinor fields in a torsional gravity, Lorentz-violating, framework
A. F. Ferrari, J. A. S. Neto, R. da Rocha
In this work, we consider a generalization of quantum electrodynamics including Lorentz violation and torsional-gravity, in the context of general spinor fields as classified in th…
Nielsen Identity and the Renormalization Group Functions in an Abelian Supersymmetric Chern-Simons Model in the Superfield Formalism
A. G. Quinto, A. F. Ferrari
In this paper we study the Nielsen identity for the supersymmetric Chern-Simons-matter model in the superfield formalism, in three spacetime dimensions. The Nielsen identity is ess…
New effects in the interaction between electromagnetic sources mediated by nonminimal Lorentz violating interactions
L. H. C. Borges, A. F. Ferrari, F. A. Barone
This paper is dedicated to the study of interactions between external sources for the electromagnetic field in a Lorentz symmetry breaking scenario. We focus on a particular higher…
Generation of higher derivatives operators and electromagnetic wave propagation in a Lorentz-violation scenario
L. H. C. Borges, A. G. Dias, A. F. Ferrari +2
We study the perturbative generation of higher-derivative operators as corrections to the photon effective action, which are originated from a Lorentz violation background. Such co…
