【 摘 要 】

Tau leptons play an essential role in the physics program at the LHC. They are used in the studies for the recently-observed Higgs boson as well as in electroweak measurements and are one of the key ingredients to search for processes predicted by theories beyond the Standard Model. Identifying hadronically decaying tau leptons with a good performance is an essential part of these analyses. The techniques of tau lepton reconstruction and identification used with the ATLAS detector are presented. The misidentification probabilities of QCD jets and electrons are determined from ATLAS data collected in 2012 and from Monte Carlo simulation.
