Experiments comparing the anomalous magnetic moments of the electron and the positron can place tight limits on $CPT$ violation. The conventional figure of merit adopted in these experiments, involving the difference between the corresponding $g$ factors, is shown to provide a misleading measure of the precision of $CPT$ limits. We introduce an alternative figure of merit, comparable to one commonly used in $CPT$ tests with neutral mesons. To measure it, a straightforward extension of current experimental procedures is proposed. With current technology, a $CPT$ bound better than about 1 part in $10^{20}$ is attainable. dc.language.iso en_US dc.publisher American Physical Society dc.relation.isversionof https://doi.org/10.1103/PhysRevLett.79.1432 dc.rights © 1997 American Physical Society. dc.title Testing $CPT$ with anomalous magnetic moments dc.type Article
