Remarks on a Lorentz-breaking 4D chiral gauge theory
A. P. Baêta Scarpelli, M. Gomes, A. Yu. Petrov +1
We investigate a Lorentz-violating chiral model composed by two fermions, a complex scalar field and a gauge field. We show that by convenientely adjusting the parameters of the mo…
Large N limit of supersymmetric Chern-Simons-matter model: breakdown of superconformal symmetry
J. M. Queiruga, A. J. da Silva
In this work we study some properties of the three dimensional SUSY Chern-Simons coupled to a scalar field in the fundamental representation in the large limit. For larg…
Lorentz breaking supersymmetry and Horava-Lifshitz-like models
M. Gomes, J. Queiruga, A. J. da Silva
We present a Lorentz-breaking supersymmetric algebra characterized by a critical exponent . Such construction requires a non trivial modification of the supercharges and superde…
Effective field theory of quantum gravity coupled to scalar electrodynamics
L. Ibiapina Bevilaqua, A. C. Lehum, A. J. da Silva
In this work we use the framework of effective field theory to couple Einstein's gravity to scalar electrodynamics and determine the renormalization of the model through the study…
On one-loop corrections in the Horava-Lifshitz-like QED
M. Gomes, T. Mariz, J. R. Nascimento +3
We study the one-loop two point functions of the gauge, scalar and spinor fields for a Horava-Lifshitz-like QED with critical exponent . It turns out that, in certain cases, t…
Superfield Effective Potential for the Supersymmetric Topologically Massive Gauge theory in Four Dimensions
F. S. Gama, M. Gomes, J. R. Nascimento +2
We explicitly calculate the one-loop effective potential for the supersymmetric topologically massive gauge theory in four dimensions, where the chiral scalar superfield is directl…
