High-precision spectroscopy with the ATLAS muon system

The ATLAS muon spectrometer will measure muon tracks along a spectrometer arm of up to 15 m length, embedded in a magnetic field of ~0.5 T. The precision tracking devices in the muon system will be high-pressure drift tubes (MDTs). To achieve a momentum resolution of ~10% for muons with a transverse...

description The ATLAS muon spectrometer will measure muon tracks along a spectrometer arm of up to 15 m length, embedded in a magnetic field of ~0.5 T. The precision tracking devices in the muon system will be high-pressure drift tubes (MDTs). To achieve a momentum resolution of ~10% for muons with a transverse momentum of p/sub T/=1 TeV/c, the systematic error to the space-time relationship has to be smaller than delta /sup r.m.s./<70 mu m. Contributions to a systematic error delta /sup r.m.s./ and its impact on the muon-momentum resolution are discussed. LHC physics require excellent knowledge of the absolute momentum scale. We show a calibration method which will achieve an accuracy at the 10/sup -4/ level. (5 refs).
