Abstract:
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.- quantum electrodynamics
- violation: Lorentz
- radiative correction
- photon: decay
- vacuum state
- amplitude analysis: on-shell
- invariance: CPT
- Feynman graph: higher-order
