1. N=2 Supersymmetry with Central Charge: A Twofold Implementation / Ospedal, L. P. R. ; Terin, R. C.
In this work, we analyze an extended N=2 supersymmetry with central charge and develop its superspace formulation under two distinct viewpoints. [...]

2. Supersymmetry and fermionic modes in an oscillon background / Correa, R.A.C. ; Ospedal, L.P.R. ; de Paula, W. ; Helayël-Neto, J.A.
The excitations referred to as oscillons are long-lived time-dependent field configurations which emerge dynamically from non-linear field theories. [...]

4. Comparative Aspects of Spin-Dependent Interaction Potentials for Spin-1/2 and Spin-1 Matter Fields / Malta, P. C. ; Ospedal, L. P. R. ; Veiga, K. ; Helayël-Neto, J. A.
This paper sets out to establish a comparative study between classes of spin- and velocity-dependent potentials for spin-1/2 and spin-1 matter currents/sources in the nonrelativistic regime. [...]

5. A 3-form gauge potential in 5D in connection with a possible dark sector of 4D-electrodynamics / Cocuroci, D. ; Neves, M. J. ; Helayël-Neto, J. A. ; Ospedal, L. P. R.
We here propose a 5-dimensional Abelian gauge model based on the mixing between a U (1) potential and an Abelian 3-form field by means of a topological mass term. [...]

6. Topologically massive spin-1 particles and spin-dependent potentials / Ferreira, F. A. Gomes ; Malta, P. C. ; Ospedal, L. P. R. ; Helayël-Neto, J. A.
We investigate the role played by particular field representations of an intermediate massive spin-1 boson in the context of spin-dependent interparticle potentials between fermionic sources in the limit of low momentum transfer. [...]
