Testing Lorentz and CPT invariance with neutrinos

TL;DR

This paper reviews how various neutrino experiments can be used to test the fundamental symmetries of Lorentz and CPT invariance, highlighting their potential to detect symmetry violations.

Contribution

It provides a comprehensive overview of experimental signatures and methods for testing Lorentz and CPT invariance using neutrino data.

Findings

Neutrino experiments can detect potential Lorentz and CPT violations.

Different types of neutrino experiments offer complementary tests.

Signatures of symmetry breakdown can be identified in neutrino oscillations and astrophysical data.

Abstract

Neutrino experiments can be considered sensitive tools to test Lorentz and CPT invariance. Taking advantage of the great variety of neutrino experiments, including neutrino oscillations, weak decays, and astrophysical neutrinos, the generic experimental signatures of the breakdown of these fundamental symmetries in the neutrino sector are presented.
