Implementation and commissioning of the ATLAS tau trigger

Moving to the high energy regime of LHC, the identification of tau leptons will become an important and very powerful tool, allowing the discovery of physics beyond the Standard Model. Tools to efficiently identify tau lepton at trigger level, based on the advanced calorimetry and tracking capabilities, have been developed for the ATLAS experiment. Commissioning of the tau trigger is presently being carried out. Tau trigger implementation, performance, and commissioning strategy is presented.
