Search for a dark matter candidate produced in association with a single top quark in pp-bar collisions at s=1.96 TeV
Original language description
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/$c^{2}$.
