Equivalence principle in the nonbaryonic regime

We consider the empirical validity of the equivalence principle for nonbaryonic matter. Working in the context of the $\mathrm{TH}\epsilon \mu$ formalism, we evaluate the constraints experiments place on parameters associated with violation of the equivalence principle (EVP’s) over as wide a sector of the standard model as possible. Specific examples include new parameter constraints which arise from torsion balance experiments, gravitational redshift, variation of the fine structure constant, time-dilation measurements, and matter-antimatter experiments. We find several new bounds on EVP’s in the leptonic and kaon sectors.
