Measurement of the tt¯ production cross-section and lepton differential distributions in eμ dilepton events from pp collisions at √s = 13TeV with the ATLAS detector

Abstract

CERN-LHC. Measurements of the absolute and fiducial differential cross-sections for single leptons and the dilepton system in ttbar production at sqrt(s)=13 TeV, decaying to the e-mu bbbar nnubar final state. The fiducial region is defined as: - opposite sign electron and muon - each lepton with pT>20 GeV and |eta|<2.5 - no requirements on jets or missing transverse energy (neutrinos) Results are provided including the contribution of leptonic tau decays, or corrected for the estimated tau contribution, corresponding to direct t->W->e/mu only
