On the effective potential, Horava-Lifshitz-like theories and finite temperature
C. F. Farias, M. Gomes, J. R. Nascimento +2
We calculate the one-loop effective potential at finite temperature for the Horava-Lifshitz-like QED and Yukawa-like theories for arbitrary values of the critical exponent and the…
Braneworld solutions for F(R) models with non-constant curvature
D. Bazeia, A. S. Lobao, R. Menezes +2
This work deal with braneworld scenarios with generalized gravity. We investigate models where the potential of the scalar field is polynomial or nonpolynomial. We obtain exact and…
Supersymmetry breaking in the three-dimensional nonlinear sigma model
A. C. Lehum, A. J. da Silva
In this work we discuss the phase structure of a deformed supersymmetric nonlinear sigma model in a three-dimensional space-time. The deformation is introduced by a term that break…
Some Generalizations in Supersymmetric Quantum Mechanics and the Supersymmetric -System Revisited
E. A. Gallegos, A. J. da Silva, D. Spehler
We discuss two distinct aspects in supersymmetric quantum mechanics. First, we introduce a new class of operators A and in terms of anticommutators between the momentum o…
Gravitational corrections to the scattering in a massless quantum electrodynamics
B. Charneski, A. C. Lehum, A. J. da Silva
We discuss the role of gravitational corrections to the running of the electric charge through the evaluation of scattering amplitudes of charged particles in massless scalar elect…
On the many-field f(R) brane
D. Bazeia, R. Menezes, A. Yu. Petrov +1
We consider the Randall-Sundrum braneworld theory with a single extra dimension of infinite extent to investigate generalized braneworld models in the presence of several re…
Supergauge theories in aether superspace
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov +1
Within the superfield method we extend the formulation of the Lorentz-breaking aether superspace for supergauge theories, both in three- and in four-dimensional cases.
