Redshift Anomalies with Universal Free-Fall

General Relativity and Quantum Cosmology 2017-08-23 v2 High Energy Physics - Phenomenology

Abstract

For most theories which parametrize modifications of General Relativity, including those which violate the equivalence principle, gravitational redshift tests typically offer weaker constraints on such test parameters than do precision measurements of the universality of free fall (UFF) and local Lorentz invariance (LLI). Although redshift anomalies are often linked with violations of UFF or LLI, they do not have to be. We offer a simple model in which particle masses anomalously vary with the gravitational potential. This generates gravitational redshift anomalies unconstrained by existing tests of UFF or LLI. We propose new experiments to limit such effects.
