摘要

The primary goal of the ANTARES telescope is the detection of high energy cosmic muon neutrinos. Theneutrinos are identified by the upward going muons that are produced in charged current neutrino interactions in thevicinity of the detector. The Cherenkov light produced by the muons in the detection volume is measured accuratelyby an array of photosensors. Muons that are going downward are background for neutrino searches. These muons arethe decay products of cosmic-ray collisions in the Earth's atmosphere. The energy loss in water of a muon with anenergy above a TeV is characterized by discrete bursts of Cherenkov light originating mostly from pair production andbremsstrahlung (electromagnetic showers). This paper presents a method to identify and count electromagnetic showersproduced by the muons. The method can be used to select a sample of highest energy muons with the ANTARES detector.
