Identification and energy calibration of hadronic tau lepton decays at the LHC

The identification of hadronic tau lepton decays is an important requirement for the LHC physics program, both in terms of standard model measurements and the search for beyond-the-standard-model physics. The ATLAS and CMS algorithms for identification and energy calibration of hadronic tau lepton decays are conceptually different. They are described together with measurements of relevant performance figures.
