Measurement of the t(t)over-bar production cross section in the tau plus jets channel using the ATLAS detector

A measurement of the top quark pair production cross section in the final state with a hadronically decaying tau lepton and jets is presented. The analysis is based on proton-proton collision data recorded by the ATLAS experiment at the LHC, with a centre-of-mass energy of 7 TeV. The data sample cor...

Description
Summary:A measurement of the top quark pair production cross section in the final state with a hadronically decaying tau lepton and jets is presented. The analysis is based on proton-proton collision data recorded by the ATLAS experiment at the LHC, with a centre-of-mass energy of 7 TeV. The data sample corresponds to an integrated luminosity of 1. 67 fb-1. The cross section is measured to be σtt̄ = 194 ± 18 (stat.) ± 46 (syst.) pb and is in agreement with other measurements and with the Standard Model prediction. © 2013 CERN for the benefit of the ATLAS collaboration.
