Tau Reconstruction and Identification in the ATLAS Experiment

This poster shows the performance of the reconstruction algorithm and identification methods for hadronically decaying tau leptons in ATLAS. The efficiency for tau lepton identification is shown, along with their dependence on various kinematic variables. Furthermore, the fake rates are measured in various samples enriched with jet backgrounds, and the identification efficiency is measured in a sample of W->tau nu decays. Comparison with data and Monte Carlo are also demonstrated.
