The Muon Combined Performance Working Group aims at optimizing and measuring the reconstruction and identification performance for muons in ATLAS. Muon reconstruction is based on the combined use of data from three subdetectors: Muon Spectrometer, Inner Detector, and Calorimeters. The activity is thus determined from the combined performance of these detectors and of the corresponding event reconstruction software, providing a link between Detector Software and Physics Analysis. The MCP activities cover three main areas: combined muon reconstruction and identification, data quality assurance, and guides for usage in physics analysis. The group collaborates closely with the Muon Trigger Signature Group.
