This paper provides a comprehensive compilation of measured and derived values of coefficients for Lorentz and CPT violation in the Standard-Model Extension (SME). The authors, V. Alan Kostelecký and Neil Russell, present 46 data tables and four summary tables that list the maximal attained sensitivities in the matter, photon, neutrino, and gravity sectors. They also provide 25 properties tables that detail the definitions and properties of the SME and the coefficients for Lorentz violation. The data tables cover various sectors, including electron, proton, neutron, photon, charged lepton, neutrino, quark, electroweak, gluon, and gravity sectors. The properties tables include information about the operator structure, discrete symmetries, and coefficient combinations in the SME. The paper aims to guide future experimental searches for Lorentz and CPT violation by providing a detailed overview of existing constraints and open directions for research.This paper provides a comprehensive compilation of measured and derived values of coefficients for Lorentz and CPT violation in the Standard-Model Extension (SME).
