Abstract

We show that in certain classes of theories the spatial variation of the non-Newtonian potential would be dominantly an exponential rather than a Yukawa potential, and we compare the phenomenological interpretation of the existing data in the exponential and Yukawa models. We also show that generalized forms of the exponential potential can arise naturally from simple mass spectra. Although such models cannot reconcile all of the existing data on non-Newtonian gravity, they have novel properties that can be directly studied experimentally.
