### Description

The Z->tautau cross-section has been measured with the ATLAS experiment at the LHC in four different channels, depending on the decays of the two tau leptons: electron-hadrons, muon-hadrons, electron-muon and muon-muon. The analysis is based on the data sample collected in 2010, corresponding to an integrated luminosity of 36 pb-1, at a proton-proton centre-of-mass energy of 7 TeV. The cross section for W->tau nu is also measured.
