The ATLAS muon and tau triggers

The ATLAS Experiment at CERN's Large Hadron Collider (LHC) deploys a three-levels processing scheme for the trigger system. The development of fast trigger algorithms and the design of topological selections are the main challenges to allowing a large program of physics analyses. In the following, two of the ATLAS trigger signatures are described: the muon and the tau triggers. The structure of the three levels of the two triggers are explained in detail as well as their performance in the first three years of data taking.
