Description
Tau leptons will play an important role in the physics program
at the LHC. They will be used not only in searches for new
phenomena like the Higgs boson or Supersymmetry and electroweak
measurements but also in detector related studies like the
determination of the missing transverse energy scale.
Identifying hadronically decaying tau leptons requires good
understanding of the detector performance, combining the calorimeter
and tracking detectors. We present the current status of the tau
reconstruction and identification at the LHC with the ATLAS detector.
The identification efficiencies are measured by W->taunu and
Z->tautau events, and compared with the prediction of the Monte Carlo
simulation. The performance of the fake tau rejection is also estimated
in jet-enriched data samples from dijets, multi-jets, gamma+jets and
Z+jets events.
