Supersymmetry and Fermionic Modes in an Oscillon Background
R. A. C. Correa, L. P. R. Ospedal, W. de Paula +1
The excitations referred to as oscillons are long-lived time-dependent field configurations which emerge dynamically from non-linear field theories. Such long-lived solutions are o…
Photon sector analysis of Super and Lorentz symmetry breaking: effective photon mass, bi-refringence and dissipation
Luca Bonetti, Luís R. dos Santos Filho, José A. Helayël-Neto +1
Within the Standard Model Extension (SME), we expand our previous findings on four classes of violations of Super-Symmetry (SuSy) and Lorentz Symmetry (LoSy), differing in the hand…
Fermion inter-particle potentials in 5D and a dimensional restriction prescription to 4D
L. P. R. Ospedal, J. A. Helayël-Neto
This work sets out to compute and discuss effects of spin, velocity and dimensionality on inter-particle potentials systematically derived from gauge field-theoretic models. We inv…
F-term spontaneous breaking of 3D-SUSY an algebro-geometric treatment
José J. Ramón Marí, Y. M. P. Gomes, J. A. Helayël-Neto
We settle a result on generic exactness of SUSY in 3-D, and provide a mechanism of F-term spontaneous breaking of 3-D SUSY, with a different set of tools from those used by O'Raife…
The protophobic -boson coupled to quantum electrodynamics
Mario J. Neves, Everton M. C. Abreu
The possible origin of an -boson having a mass value around $17 \, \mbox{MeV}$ had motivated us to investigate its interaction with leptons of QED. This new hypothetical particl…
Structural scale derivative and the LLG-Equation in a scenario with fractionality
José Weberszpil, José Abdalla Helayël-Neto
In the present contribution, we study the Landau-Lifshitz-Gilbert equation with two versions of structural derivatives recently proposed: the scale derivative in the non-extens…
The bosonized version of the Schwinger model in four dimensions: a blueprint for confinement?
Antonio Aurilia, Patricio Gaete, José A. Helayël-Neto +1
For a -dimensional generalization of the Schwinger model, we compute the interaction energy between two test charges. The result shows that the static potential profile cont…
The origin of Chern-Simons modified gravity from an 11 + 3-dimensional manifold
J. A. Helayël-Neto, Alireza Sepehri
In this contribution, it is our aim to show that the Chern-Simons terms of modified gravity can be understood as generated by the addition of a 3-dimensional algebraic manifold to…
