CPT violation implies violation of Lorentz invariance.
A 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.
متن کاملData tables for Lorentz and CPT violation
Recent years have seen a renewed interest in experimental tests of Lorentz and CPT symmetry. Observable signals of Lorentz and CPT violation can be described in a modelindependent way using effective field theory (Kostelecký and Potting, 1995). The general realistic effective field theory for Lorentz violation is called the standard-model extension (SME) (Colladay and Kostelecký, 1997; 1998; Ko...
متن کاملSuperfield Realizations of Lorentz and CPT Violation
Superfield realizations of Lorentz-violating extensions of the Wess-Zumino model are presented. These models retain supersymmetry but include terms that explicitly break the Lorentz symmetry. The models can be understood as arising from superspace transformations that are modifications of the familiar one in the Lorentz-symmetric case.

متن کاملTopics in Lorentz and Cpt Violation
Invariance under Lorentz and CPT transformations is a fundamental requirement of local relativistic quantum field theories, including the standard model of particle physics. This invariance also seems to be realized in nature, as no clear signals for violations have been observed despite numerous experimental tests. Nonetheless, several facts offer motivation for theoretical studies of possible...
