Post-Newtonian Gravity with Lorentz Violation

Lorentz-symmetry violation is a popular candidate signal for Planck-scale physics. The general description of observable Lorentz-symmetry violation at low energies is given by the Standard-Model Extension (SME). This talk discusses the pure gravitational sector of the SME in the limit of Riemann geometry and presents some key results for the post-newtonian limit. We outline several promising possibilities for experimental searches, including some with the potential to access unmeasured coefficients for Lorentz violation and others that could improve existing sensitivities.
