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…
Subtleties in the beta function calculation of N=1 supersymmetric gauge theories
A. L. Cherchiglia, Marcos Sampaio, B. Hiller +1
We investigate some peculiarities in the calculation of the two-loop beta-function of supersymmetric models which are intimately related to the so-called "Anomaly Puzzle". Th…
On the anomalies in Lorentz-breaking theories
A. P. Baeta Scarpelli, T. Mariz, J. R. Nascimento +1
In this paper, we discuss the chiral anomaly in a Lorentz-breaking extension of QED which, besides the common terms that are present in the Standard Model Extension, includes some…
