Scale Anomaly in Supersymmetric Quantum Electrodynamics: Ward Identities, Supersymmetry Breaking, and Decoupling
A. Yu. Petrov, A. R. Vieira
We study the breaking of the scale symmetry both within classical and quantum frameworks in the supersymmetric quantum electrodynamics (SQED) by applying a four-dimensional regular…

Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation
A. Yu. Petrov, M. Schreck, A. R. Vieira
Vacuum Cherenkov radiation is investigated in the Lorentz-violating Standard-Model Extension for isotropic dim-5 operators and in the fermion sector. Both the…

Gauge symmetry and radiatively induced terms in dimension-5 non-minimal Lorentz-violating QED
A. P. B. Scarpelli, A. R. Vieira
In this work, we derive the conditions that assure gauge invariance of a non-minimal dimension-5 Lorentz-violating QED. The two and three point functions at one-loop are computed.…
