Particle Physics Implications of a Recent Test of the Gravitational Inverse Square Law

Abstract

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 interactions. We test the interpretation of the PVLAS effect and a conjectured ``fat graviton'' scenario and constrain the ${\gamma }_5$ couplings of pseuodscalar bosons and arbitrary power-law interactions.
