Measurement of the pp̄→tt̄+X production cross section at s=1.96TeV in the fully hadronic decay channel

Abstract:

A measurement of the top quark pair production cross section in proton antiproton collisions at an interaction energy of s=1.96TeV is presented. This analysis uses 405±25pb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider. Fully hadronic tt̄ decays with final states of six or more jets are separated from the multijet background using secondary vertex tagging and a neural network. The tt̄ cross section is measured as σtt̄=4.5-1.9+2.0(stat)-1.1+1.4(syst)±0.3(lumi)pb fo...
