Complete-Coverage Searches for Lorentz Violation in the Minimal Matter Sector

Over the past several decades, dozens of tests have sought the 132 Lorentz-violating degrees of freedom in the nonrelativistic limit of the minimal matter sector of the Standard-Model Extension, yet 43 remained unconstrained. In this Letter, we limit all previously unconstrained degrees of freedom and make improvements on 13 prior limits. The approach introduced here offers the potential of further improvements for 49 degrees of freedom in suitable future experiments, along with additional discovery potential offered by combining data from experiments performed in different locations.

Achieving Full Coverage of the SME Minimal Matter Sector

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.
