abstract
An interacting theory that violates CPT invariance necessarily violates Lorentz invariance. On the other hand, CPT invariance is not sufficient for out-of-cone Lorentz invariance. Theories that violate CPT by having different particle and antiparticle masses must be nonlocal.

Combined CPT-violating and CPT-conserving Lorentz-invariance-violation parameters suppress DUNE's CP-violation sensitivity below 3σ over much of the δ_CP range and introduce parameter degeneracies that complicate δ_CP extraction.
CPT-odd Lorentz-violating scalar QCD is multiplicatively renormalizable at one loop, with all divergences absorbed into existing counterterms and explicit beta functions obtained.
