Achieving Full Coverage of the SME Minimal Matter Sector

Abstract

Existing experiments and data sets can be leveraged to obtain additional sensitivities to Lorentz violation, beyond those originally sought, through a more precise consideration of the boost of the experiment through the background. In fact, access to the full coefficient space of the flat-spacetime single-fermion limit of the minimal matter sector of the Standard-Model Extension can be obtained. In this work we present this coverage for a sample particle in the context of a simplified model of Earth's motion.
