What is Top cross section measurements at ATLAS about?

Measurements of the production cross section of top-quark pairs ($t\bar t$) in $pp$ collisions at $\sqrt{s}$ = 7 TeV are presented using 35 \ipb\ of data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in the single lepton (electron or muon) and dilepton topologies with multi-jets, and large missing transverse energy. The result is $\sigma_{t\bar t} = 180 \pm 9\,\mathrm{(stat.)} \pm15 \,\mathrm{(syst.)} \pm 6 \,\mathrm{(lumi.)\,pb}$, which agrees with the Standard Model prediction.
