dc.descriptionThe top quark pair production cross-section $σ_{t\bar{t}}$ has been measured in $p\bar{p}$ collisions at center of mass energies of 1.96 TeV using Tevatron Run 2 data. In the begining of Run 2 both CDF and DØ $σ_{t\bar{t}}$ measurements in the {\it dilepton} channel $t\bar{t}{\to}WbW\bar{b}{\to}\bar{\ell}ν_{\ell}b{\ell}^{'}\ barν_{{\ell}^{'}}\bar{b}$ and in the {\it lepton plus jets} channel $t\bar{t}{\to}WbW\bar{b}{\to}q\bar{q}^{'}b{\ell}\barν_{\ell }\bar{b}+\bar{\ell}ν_{\ell}bq\bar{q}^{'}\bar{b}$ agree with the NLO (Next-to-Leading-Order) theoretical predictions. The presence of a top signal in Tevatron data has been reestablished.
