We present the results of a search for dark matter production in
the monojet signature. We analyze a sample of Tevatron pp̅ collisions
at √s=1.96 TeV corresponding to an integrated luminosity of
6.7 fb-1 recorded by the CDF II detector. In events with large
missing transverse energy and one energetic jet, we find good agreement
between the standard model prediction and the observed data. We set 90%
confidence level upper limits on the dark matter production rate. The
limits are translated into bounds on nucleon-dark matter scattering
rates which are competitive with current direct detection bounds on
spi+n-independent interaction below a dark matter candidate mass of
5 GeV/c2, and on spi+n-dependent interactions up to masses of
200 GeV/c2.
