We present a measurement of the top-quark pair production cross-section in the tau+lepton channel in proton-proton collisions at 7 TeV with the ATLAS detector at the Large Hadron Collider. Events with an isolated electron or muon and a tau lepton decaying hadronically are used. In addition, a large missing transverse momentum and two or more energetic jets are required. At least one of the jets must be identified as originating from a b quark. To identify tau leptons, the analysis uses a multivariate technique based on boosted decision trees.
