Book excerpt: The top quark pair production cross-section[sigma][sub t[bar t]] has been measured in p[bar p] collisions at center of mass energies of 1.96 TeV using Tevatron Run 2 data. In the beginning of Run 2 both CDF and D0[sigma][sub t[bar t]] measurements in the dilepton channel t[bar t][yields] WbW[bar b][yields][bar[ell]][nu][sub[ell]]b[ell][prime][bar[nu]][sub[ell][prime]][bar b] and in the lepton plus jets channel t[bar t][yields] WbW[bar b][yields] q[bar q][prime] b[ell][bar[nu]][sub[ell]][bar b]+[bar[ell]][nu][sub[ell]]bq[bar q][prime][bar b] agree with the NLO (Next-to-Leading-Order) theoretical predictions. The presence of a top signal in Tevatron data has been reestablished.
