Description
The first two years of p-p collisions at sqrt(s)=7 TeV at LHC have
provided a rich data sample with which the muon performance of the ATLAS detector could be measured in high detail. Decays of Z, W and J/psi particles to muons are used, corresponding to an integrated luminosity of 40pb^-1 in 2010 and 2.5fb^-1 in 2011. The muon identification, reconstruction and trigger efficiencies are reported and compared to the expectation from current ATLAS simulation. ATLAS is designed for a precise muon momentum determination up to transverse momenta of 1 TeV. Measurements of the muon momentum scale and resolution are presented and discussed under aspects of alignment and inter-alignment of the charged particle detectors in ATLAS.
