Additional information

The letter presents a measurement of the top quark pair production cross section using the dilepton channel, in which both W bosons (produced from top quarks) decay to leptons. Candidate events exhibit unbalanced transverse momentum, indicating the presence of neutrinos from the W-boson decays . The selection of events consists of a series of kinematic requirements on the reconstruction. The optimisation (by Watson) of missing transverse energy and lepton identification, performed on simulated event samples to obtain maximum statistical significance, were critical components of the cross-section measurement. The publication includes ten times more data than the previous ATLAS observation.
