Measurement of the t t production cross section in the τ+jets final state in pp collisions at s =8 TeV using the ATLAS detector

A measurement of the inclusive pp→tt+X production cross section in the τ+jets final state using only the hadronic decays of the τ lepton is presented. The measurement is performed using 20.2 fb-1 of proton-proton collision data recorded at a center-of-mass energy of s=8 TeV with the ATLAS detector a...
