TL;DR

This paper explores testing the Einstein Equivalence Principle through anomalous magnetic moment measurements, revealing new mechanisms for EEP violation arising from radiative corrections in non-metric gravity theories.

Contribution

It introduces novel mechanisms for EEP violation caused by radiative corrections in non-metric gravity models and discusses potential empirical constraints.

Findings

Identified new EEP violation mechanisms from radiative effects.

Computed one-loop corrections for the g-2 anomaly in non-metric theories.

Suggested ways to empirically test these EEP violations.

Abstract

We investigate the possibility of testing of the Einstein Equivalence Principle (EEP) using measurements of anomalous magnetic moments of elementary particles. We compute the one loop correction for the $g-2$ anomaly within the class of non metric theories of gravity described by the \tmu formalism. We find several novel mechanisms for breaking the EEP whose origin is due purely to radiative corrections. We discuss the possibilities of setting new empirical constraints on these effects.
