Measurements of ttbar production cross-section with D0 experiment
Abstract
The recent measurements of the top anti-top quark pair production cross-section in proton antiproton collisions at sqrts=1.96 TeV in lepton + jets and dilepton (including tau lepton) channels are presented. These measurements are based on 1 fb-1 of data collected with the DO experiment at the Fermilab Tevatron collider. The measured values are compatible with the standard model prediction and have the uncertainty close to the uncertainty of the theoretical prediction ~10%.
