Query: The Standard-Model Extension and Tests of Relativity   The Standard-Model Extension, or SME, is a general framework for the study of
Lorentz violation in physics. A broad variety of experiments is able to access
the SME coefficient space. This proceedings briefly summarizes theory and
experiments aimed at testing Special Relativity by measuring these
coefficients.
