Phys. Rev. D 79, 023504 (2009) [11 pages]Dilatonic dark matter and its experimental detectionReceived 9 October 2008; published 7 January 2009 Assuming that the dilaton is the dark matter of the Universe, we propose an experiment to detect the relic dilaton using the electromagnetic resonant cavity, based on the dilaton-photon conversion in strong electromagnetic background. We calculate the density of the relic dilaton, and estimate the dilaton mass for which the dilaton becomes the dark matter of the Universe. With this we calculate the dilaton detection power in the resonant cavity, and compare it with the axion detection power in a similar resonant cavity experiment. © 2009 The American Physical Society URL:
