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.…
