$C P T$ Violation Implies Violation of Lorentz Invariance

Phys. Rev. Lett. 89, 231602 – Published 18 November 2002

Abstract

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