Inclusive and Differential $t\bar{t}$ Cross Section Measurements with the ATLAS and CMS experiments

The inclusive top pair production cross section ${\sigma}_{t\bar{t}}$ measurements with the data samples of proton proton collisions produced by the LHC (Large Hadron Collider) during the Run 1 at center of mass energies of $\sqrt{s}$ = 7 and 8 TeV, have reached an experimental accuracy without precedents. The best single ${\sigma}_{t\bar{t}}$ measurements are carried out in the dilepton $e{\mu}$ channel. Recent ${\sigma}_{t\bar{t}}$ measurements at $\sqrt{s}$ = TeV are reviwed. All these measurements are in good agreement with the Standard Model (SM). Differential cross section measurements as function of kinematic properties of top quarks and $t\bar{t}$ system as well as top quark decay products show no significant deviations from the SM predictions.
