We use data from our recent search for violations of the gravitational inverse-square law to constrain dilaton, radion, and chameleon exchange forces as well as arbitrary vector or scalar Yukawa interactions. We test the interpretation of the PVLAS Collaboration effect and a conjectured “fat-graviton” scenario and constrain the γ5 couplings of pseuodscalar bosons and arbitrary power-law interactions.
