We discuss the regularization and renormalization of QED with Lorentz and CPT violation, and argue that the coefficient of the Chern-Simons term is an independent parameter not determined by gauge invariance. We also study these issues in a model with spontaneous breaking of Lorentz and CPT symmetries and find an explicit relation with the ABJ anomaly. This explains the observed convergence of the induced Chern-Simons term.

  1. Crystallography, Lorentz violation, and the Standard-Model Extension

    cond-mat.mes-hall 2026-04 unverdicted novelty 6.0

    Crystal point groups parametrize SME Lorentz-violating coefficients in electromagnetic media, turning birefringent and multiferroic crystals into analogs for high-energy symmetry violations.

  2. Perturbative Analysis of CPT-Odd Lorentz-Violating Scalar QCD

    hep-th 2026-05 unverdicted novelty 5.0

    CPT-odd Lorentz-violating scalar QCD is multiplicatively renormalizable at one loop, with all divergences absorbed into existing counterterms and explicit beta functions obtained.
