Measurement of the tt? production cross section using dilepton events in pp? collisions
Original language description
We present a measurement of the View the MathML source production cross section View the MathML source in View the MathML source collisions at View the MathML source using 5.4 fb1 of integrated luminosity collected with the D0 detector. We consider finalstates with at least two jets and two leptons (ee, e?, ??), and events with one jet for the e? final state as well. The measured cross section is View the MathML source. This result combined with the cross section measurement in the lepton + jets finalstate yields View the MathML source, 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.
