Vacuum photon splitting in Lorentz-violating quantum electrodynamics

Vacuum photon splitting in Lorentz-violating quantum electrodynamics

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 CPT-even and CPT-odd contributions forbidden in conventional electrodynamics.
