Experimental Tests of Local Lorentz Invariance

Lorentz invariance, fundamental to Relativity and the Standard Model, has been thoroughly investigated both theoretically and experimentally in the past 15 years. This investigation, motivated in large by attempts to unify gravity with the Standard Model through quantum gravity, has led to strict constraints on the nature and size of a violation. A historical perspective of Lorentz’s work, a brief discussion of the theoretical framework, and a discussion of high-precision tests and their results are presented.
