EQUIVALENCE PRINCIPLE IN THE NONBARYONIC REGIME

We consider the empirical validity of the equivalence principle for no nbaryonic matter. Working in the context of the TH epsilon mu. formali sm, we evaluate the constraints experiments place on parameters associ ated 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, ti me-dilation measurements, and matter-antimatter experiments. We find s everal new bounds on EVP's in the leptonic and kaon sectors.
