Abstract: For most theories which parametrize modifications of General Relativity,including those which violate the equivalence principle, gravitational redshifttests typically offer weaker constraints on such test parameters than doprecision measurements of the universality of free fall UFF and local Lorentzinvariance LLI. Although redshift anomalies are often linked with violationsof UFF or LLI, they do not have to be. We offer a simple model in whichparticle masses anomalously vary with the gravitational potential. Thisgenerates gravitational redshift anomalies unconstrained by existing tests ofUFF or LLI. We propose new experiments to limit such effects.
