  We study a model in which dark matter couples to the Standard Model through a
dilaton of a sector with spontaneously broken approximate scale invariance.
Scale invariance fixes the dilaton couplings to the Standard Model and dark
matter fields, leaving three main free parameters: the symmetry breaking scale
$f$, the dilaton mass $m_{\sigma}$, and the dark matter mass $m_{\chi}$. We
analyze the experimental constraints on the parameter space from collider,
direct and indirect detection experiments including the effect of Sommerfeld
enhancement, and show that dilaton exchange provides a consistent, calculable
framework for cold dark matter with $f,\,m_\sigma,\,m_\chi$ of roughly similar
magnitude and in the range $\sim 1-10$ TeV. Direct and indirect detection
experiments, notably future ground-based gamma ray and space-based cosmic ray
measurements, can probe the model all the way to dark matter mass in the
multi-TeV regime.
