Measurement of lepton differential distributions and the top quark mass in tt production in pp collisions at √s = 8 TeV with the ATLAS detector



    CERN-LHC. Measurements of the absolute and fiducial differential cross-sections for single leptons and the dilepton system in ttbar production at sqrt(s)=8 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>25 GeV and |eta|<2.5
    - no requirements on jets or missing transverse energy (neutrinos)

    Results are provided including the contribution of leptonic tau decays, and corrected for the estimated tau contribution, corresponding to direct t->W->e/mu only.
