Abstract

The ATLAS experiment at CERN's Large Hadron Collider (LHC) deploys a three-level processing scheme for the trigger system. The development of fast trigger algorithms and the design of topological selections are the main challenges to allow for 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 these two trigger signatures are explained in detail as well as their performance during the first three years of operation.
