Phys. Rev. Lett. 103, 011301 (2009) [4 pages]Dark-Matter-Induced Violation of the Weak Equivalence PrincipleReceived 30 July 2008; revised 15 October 2008; published 1 July 2009 A long-range fifth force coupled to dark matter can induce a coupling to ordinary matter if the dark matter interacts with standard model fields. We consider constraints on such a scenario from both astrophysical observations and laboratory experiments. We also examine the case where the dark matter is a weakly interacting massive particle, and derive relations between the coupling to dark matter and the coupling to ordinary matter for different models. Currently, this scenario is most tightly constrained by galactic dynamics, but improvements in Eötvös experiments can probe unconstrained regions of parameter space. © 2009 The American Physical Society URL:
