On the Electric Charge Quantization from the Dirac-Aharonov-Bohm Potential
F. A. Barone, J. A. Helayel-Neto
The purpose of this paper is to show that, under certain restrictions, we can take a Dirac-Aharonov-Bohm potential as a pure gauge field. We argue that a modified quantization cond…
Off-Shell Extended Supersymmetries and Lorentz-Violating Abelian Gauge Models
Wander G. Ney, J. A. Helayel-Neto, Wesley Spalenza
In this work, we propose the N=2 and N=4 supersymmetric extensions realized off-shell of the Abelian gauge model with Chern-Simons Lorentz-breaking term. We start with the theory i…
Hyperbolic Space Forms and Orbifold Compactification in M-Theory
A. A. Bytsenko, M. E. X. Guimaraes, J. A. Helayel-Neto
We analyze solutions of string theory and supergravity which involve real hyperbolic spaces. Examples of string compactifications are given in terms of hyperbolic coset spaces of f…
