On the decoupling of heavy states in higher-derivative supersymmetric field theories
M. Cvetic, T. Mariz, A. Yu. Petrov
We study the problem of decoupling of heavy chiral superfields in four-dimensional supersymmetric field theories with Lorentz-invariant and Lorentz-violating higher-derivativ…
Radiatively induced CPT-odd Chern-Simons term in massless QED
J. F. Assuncao, T. Mariz
In this work, we study the radiative generation of the CPT-odd Lorentz-violating Chern-Simons term, arising from massless fermions. For this, we calculate the vacuum polarization t…
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…
On the Adler-Bell-Jackiw anomaly in a Horava-Lifshitz-like QED
T. Mariz, J. R. Nascimento, A. Yu. Petrov
We show the absence of the ABJ anomaly for the Horava-Lifshitz-like QED with any even . Besides of this, we study the graph contributing to the ABJ anomaly at non-zero temperatu…
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…
