Abstract: (arXiv)

We report a new search for dark matter in a data sample of an integrated luminosity of 7.7 fb

^{-1}

of Tevatron

p\bar{p}

collisions at

\sqrt{s} = 1.96

TeV, collected by the CDF II detector. We search for production of a dark matter candidate,

D

, in association with a single top quark. We consider the hadronic decay mode of the top quark exclusively, yielding a final state of three jets with missing transverse energy. The data are consistent with the standard model; we thus set 95% confidence level upper limits on the cross section of the process

p\bar{p}\rightarrow t+D

as a function of the mass of the dark-matter candidate. The limits are approximately 0.5 pb for a dark-matter particle with mass in the range of 0-150 GeV/

c^{2}
