# Data Tables for Lorentz and CPT Violation

The general realistic effective field theory
for Lorentz violation is called the Standard-Model Extension (SME).
It includes the Standard Model coupled to General Relativity along with all
possible operators for Lorentz violation.
Each operator for Lorentz violation is controlled by a coefficient.
In practice, testing Lorentz symmetry means
experimentally measuring these coefficients.
This large coefficient space has been the subject of
numerous precision experiments in recent years.
The work listed below is a tabulation of these results.

This November 2020 Editorial in Nature Reviews Physics
discusses the role of curated data in physics, including these Data Tables.
