Aspects of the gauge boson-gaugino mixing in a supersymmetric scenario with Lorentz-symmetry violation
R. C. Terin, W. Spalenza, H. Belich +1
We write down an supersymmetric extension for non-Abelian gauge theories in (1+3) dimensions with a Lorentz- and CPT-violating term of the Carroll-Field-Jackiw type…
An infinite square-well potential as a limiting case of a finite square-well potential in a minimal-length scenario
André Oakes O. Gonçalves, Michael F. Gusson, Bernardo B. Dilem +4
One of the most widely problem studied in quantum mechanics is of an infinite square-well potential. In a minimal-length scenario its study requires additional care because the bou…
Effective models of quantum gravity induced by Planck scale modifications in the covariant quantum algebra
G. P. de Brito, P. I. C. Caneda, Y. M. P. Gomes +2
In this paper we introduce a modified covariant quantum algebra based in the so-called Quesne-Tkachuk algebra. By means of a deformation procedure we arrive at a class of higher de…
Aspects of CPT-even Lorentz-symmetry violating physics in a supersymmetric scenario
H. Belich, L. D. Bernald, Patricio Gaete +2
Background fermion condensates in a landscape dominated by global SUSY are reassessed in connection with a scenario where Lorentz symmetry is violated in the bosonic sector (actual…
An investigation of the -type Lorentz-Symmetry Breaking Gauge Models with Vortex-like Configurations
H. Belich, F. J. L. Leal, H. L. C. Louzada +1
For the CPT-even case of the minimal Standard Model Extension, the spin-projector method is adopted to account for the breaking (tensor) term. We adopt a particular de…
Gribov as a Phase Transition
L. C. Q. Vilar, O. S. Ventura, V. E. R. Lemes
Our goal will be the description of a theory of Gribov's type as a physical process of phase transition in the context of a spontaneous symmetry breaking. We mainly focus at the qu…
