Query: No one-loop gauge anomalies for a Lorentz-violating quantum
  electrodynamics: Evaluation of the three-photon vertex   Identification of the diagrams that can lead to gauge anomalies in the
(minimal) Lorentz- and $CPT$-violating extension of quantum electrodynamics
reveals these are the electron self-energy and vertex correction (related to
the Ward-Takahashi identity), the photon self-energy (related to the vacuum
polarization tensor transversality), and the three-photon vertex diagrams. All
but the latter were explicitly verified to be free of anomalies to first order
in loop expansion. Here we provide this remaining evaluation and verify the
absence of anomalies in this process.
