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…

CPT and Lorentz Violation in Neutral-Meson Oscillations
Alan Kostelecky
In this talk, the status of CPT tests with neutral mesons is reviewed in the context of quantum field theory and the Lorentz- and CPT-violating standard-model extension.
