Data Tables for Lorentz and CPT Violation
Alan Kostelecky, Neil Russell
TL;DR
The paper addresses the need for standardized, comprehensive tabulations of SME coefficients describing Lorentz and CPT violation. It assembles 48 data tables of experimental measurements and theoretical limits, along with 25 properties tables, and provides four summary tables that give maximal 2σ sensitivities under single-coefficient assumptions across matter, photon, neutrino, and gravity sectors. The methodology systematically aggregates results up to 2025, with careful definitions, operator classifications, and guidance on interpretation. This resource enables systematic searches, cross-sector comparisons, and identifies open directions for future tests of Lorentz/CPT symmetry.
Abstract
This work tabulates measured and derived values of coefficients for Lorentz and CPT violation in the Standard-Model Extension. Summary tables are extracted listing maximal attained sensitivities in the matter, photon, neutrino, and gravity sectors. Tables presenting definitions and properties are also compiled.
