Abstract

A measurement of the top quark pair production cross section in proton antiproton collisions at an interaction energy of

\sqrt{s} = 1.96 TeV

is presented. This analysis uses

405 \pm 25 {pb}^{- 1}

of data collected with the D0 detector at the Fermilab Tevatron Collider. Fully hadronic

t \bar{t}

decays with final states of six or more jets are separated from the multijet background using secondary vertex tagging and a neural network. The

t \bar{t}

cross section is measured as

σ_{t \bar{t}} = {4.5}_{- 1.9}^{+ 2.0} (stat)_{- 1.1}^{+ 1.4} (syst) \pm 0.3 (lumi) pb

for a top quark mass of

m_{t} = 175 GeV / c^{2}

.
