Measurement of the tt¯ production cross section using dilepton events in pp¯ collisions
Year: 2011
Type: article
Abstract: We present a measurement of the t t ¯ production cross section σ t t ¯ in p p ¯ collisions at s = 1.96 TeV using 5.4 fb − 1 of integrated luminosity collected with the D0 detector. We consider final states with at least two jets and two leptons ( ee , eμ , μμ ), and events with one jet for the eμ final state as well. The measured cross section is σ t t ¯ = 7.36 − 0.79 + 0.90 ( stat + syst ) pb . This result combined with the cross section measurement in the lepton + jets final state yields σ t t ¯ = 7.56 − 0.56 + 0.63 ( stat + syst ) pb , which agrees with the standard model expectation. The relative precision of 8% of this measurement is comparable to the precision of the latest theoretical calculations.
