Expanding the Reach of Laboratory SME Searches Using Higher-Precision Boost Transformations

Abstract

Additional sensitivities to Lorentz violation can be obtained from existing experiments by considering additional boost-suppressed effects. The additional Lorentz-violating signals arise as variations in experimental observables at the commonly-used sidereal frequency as well as more novel frequencies. In this work we provide some examples that serve to illustrate how interesting signals arise from the structure of the relevant boost transformations.
