Phenomenological implications of a magnetic 5th force

Abstract

A 5th force coupling to baryon number [Formula: see text] has been proposed to account for the correlations between the acceleration differences [Formula: see text] of the samples studied in the Eötvös experiment, and the corresponding differences in the baryon-to-mass ratios [Formula: see text]. To date the Eötvös results have not been supported by modern experiments. Here, we investigate the phenomenological implications of a possible magnetic analog [Formula: see text] of the conventional 5th force electric field, [Formula: see text], arising from the Earth’s rotation. We demonstrate that, in the presence of couplings proportional to [Formula: see text], both the magnitude and direction of a possible 5th force field could be quite different from what would otherwise be expected and warrants further investigation.
