Relativity tests and their motivation

Abstract

Some motivations for Lorentz-symmetry tests in the context of quantum-gravity phenomenology are reiterated. The description of the emergent low-energy effects with the Standard-Model Extension (SME) is reviewed. The possibility of constraining such effects with dispersion-relation analyses of collider data is established.
