In this paper we report a measurement of the tt-bar production
cross section in p anti-p collisions at s**(1/2) �.96 TeV using data
corresponding to an integrated luminosity of 2.2 fb-1 collected with
the CDF II detector at the Tevatron accelerator. We select events with
significant missing transverse energy and high jet multiplicity. This
measurement vetoes the presence of explicitly identified electrons and
muons, thus enhancing the tau contributions of t anti-t decays. Signal
events are discriminated from the background using a neural network,
and heavy flavor jets are identified by a secondary-vertex tagging
algorithm. We measure a t anti-t production cross section of 7.99 +/-
0.55(stat) +/- 0.76 (syst) +/- 0.46 (lumi) pb, assuming a top mass m_top
�72.5 GeV/c2, in agreement with previous measurements and standard
model predictions.
