On the higher-derivative Lorentz-breaking terms
T. Mariz, J. R. Nascimento, A. Yu. Petrov
The first one-loop higher-derivative contribution to the effective action of the Lorentz-breaking spinor QED is obtained and shown to be finite and ambiguous.
On the effective superpotential in the supersymmetric Chern-Simons theory with matter
M. Gomes, A. C. Lehum, J. R. Nascimento +2
We develop a superfield approach to the effective potential in the supersymmetric Chern-Simons theory coupled to matter, and, in Landau gauge, calculate the one-loop Kahlerian effe…
On the effective potential for Horava-Lifshitz-like theories with the arbitrary critical exponent
C. F. Farias, J. R. Nascimento, A. Yu. Petrov
We calculate the one-loop effective potential for Horava-Lifshitz-like QED and Yukawa-like theory for arbitrary values of the critical exponent and the space-time dimension.
On the superfield supersymmetric aether-like Lorentz-breaking models
C. F. Farias, A. C. Lehum, J. R. Nascimento +1
Within the superfield approach, we formulate the superfield supersymmetric aether-like Lorentz-breaking models, both in three- and in four-dimensional cases.
The Godel metric in the Chern-Simons modified gravity
C. Furtado, T. Mariz, J. R. Nascimento +2
We discuss the consistency of the Godel metric within the Chern-Simons modified gravity, both for external and dynamical Chern-Simons coefficients.
Dynamical generation of mass in the noncommutative supersymmetric Schwinger model
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov
Within the superfield formalism, we study the dynamical generation of mass to the gauge superfield in the noncommutative two-dimensional supersymmetric Schwinger model. We show tha…
