Resumen:
Muons from cosmic-ray interactions in the atmosphere provide a
high-statistics source of particles that can be used to study the
performance and calibration of the ATLAS detector. Cosmic-ray muons can
penetrate to the cavern and deposit energy in all detector subsystems.
Such events have played an important role in the commissioning of the
detector since the start of the installation phase in 2005 and were
particularly important for understanding the detector performance in
the time prior to the arrival of the first LHC beams. Global cosmic-ray
runs were undertaken in both 2008 and 2009 and these data have been
used through to the early phases of collision data-taking as a tool for
calibration, alignment and detector monitoring. These large datasets
have also been used for detector performance studies, including
investigations that rely on the combined performance of different
subsystems. This paper presents the results of performance studies
related to combined tracking, lepton identification and the
reconstruction of jets and missing transverse energy. Results are
compared to expectations based on a cosmic-ray event generator and a
full simulation of the detector response.
