Testing Lorentz Symmetry With Gravity, Quentin G. Bailey Aug 2007

Testing Lorentz Symmetry With Gravity, Quentin G. Bailey

Publications

In this talk, results from the gravitational sector of the Standard-Model Extension (SME) are discussed. The weak-field phenomenology of the resulting modified gravitational field equations is explored. The application of the results to a variety of modern gravity experiments, including lunar laser ranging, Gravity Probe B, binary pulsars, and Earth-laboratory tests, shows promising sensitivity to gravitational coefficients for Lorentz violation in the SME.
