Theory and Tests of CPT and Lorentz Violation

TL;DR

This paper discusses a comprehensive Lorentz-violating extension of the standard model, exploring theoretical foundations and experimental implications of CPT and Lorentz symmetry violations in particle physics.

Contribution

It introduces a general framework for Lorentz and CPT violation in the standard model, including both CPT-even and CPT-odd effects, and summarizes theoretical and experimental aspects.

Findings

Theoretical formulation of Lorentz-violating extensions.

Implications for experimental tests of Lorentz and CPT symmetry.

Summary of potential observable effects in particle physics experiments.

Abstract

A general Lorentz-violating extension of the standard model of particle physics, allowing for both CPT-even and CPT-odd effects, is described. Some of its theoretical aspects and experimental implications are summarized.
