High Precision Fundamental Physics Experiments at JLab with Spin-transparent Storage Rings of Low-energy Polarized Electron Beams
Vladimir Khachatryan, Riad Suleiman, Alberto Accardi +27
A breakthrough in fundamental physics experiments measuring particle spin precession may happen if spin-transparent storage rings become adopted tools for such experiments. We pres…

Vacuum Cherenkov Radiation for Nonminimal Isotropic Lorentz Violation
Albert Yu. Petrov, Marco Schreck, Alexandre R. Vieira
In this work, we study the effects of vacuum Cherenkov radiation caused by nonminimal dimension-5 Lorentz-violating (LV) operators in the fermion sector. Explicitly, we focus on tw…

Scale anomaly in a Lorentz and CPT-violating Quantum Electrodynamics
J. S. Porto, A. R. Vieira
We compute the classical and the quantum breaking of the dilatation current in the minimal Lorentz and CPT-violating quantum electrodynamics. At the classical level, scale symmetry…
