Vacuum Photon Splitting in Lorentz-Violating Quantum Electrodynamics
Alan Kostelecky, Austin Pickering
Radiative corrections arising from Lorentz violation in the fermion sector induce a nonzero amplitude for vacuum photon splitting. At one loop, the on-shell amplitude acquires both…

Lorentz Violation at One Loop
Austin G. M. Pickering
The proof of one-loop renormalizability of the general Lorentz- and CPT-violating extension of quantum electrodynamics is described. Application of the renormalization-group method…
