"Physics including muons at ATLAS/LHC" N. Benekos (CERN)

The ATLAS detector, currently being installed at CERN, is designed to make precise measurements of 14 TeV proton-proton collisions at the LHC, starting in 2007. Arguably the clearest signatures for new physics, including the Higgs Boson and supersymmetry, will involve the production of isolated final-stated muons. The identification and precise reconstruction of muons are performed using a combination of detector components, including an Inner Detector, comprising a silicon tracker, pixel detector, and transition radiation tracker, housed in a uniform solenoidal field, and a precision Muon Spectrometer, comprising monitored drift tubes and cathode strip chambers, triggered by resistive plate chambers and thingap chambers, and housed in a toroidal field. This paper, starting from a short update on the Muon Spectrometer and its Simulation, presents the recently developed MuonValidation package, describing four of the algorithms therein. These algorithms have been developed as tools designed to monitor and validate the performance of the Hit and Digit creation for the Muon System. Their flexible design allows comparisons between different Muon geometrical layouts or ATHENA releases.
