Zenith distribution and flux of atmospheric muons measured with the 5-line ANTARES detector
نویسنده
چکیده
The ANTARES high energy neutrino telescope is a three-dimensional array of about 900 photomultipliers distributed over 12 mooring lines installed in the Mediterranean Sea. Between February and November 2007 it acquired data in a 5 -line confi guration. The zenith angular distribution of the atmospheric muon fl ux and the associated depth-intensity relation are measured and compared with previous measurements and Monte Carlo expectations. An evaluation of the systematic effects due to uncertainties on environmental and detector parameters is presented.

The ANTARES Neutrino Telescope
The ANTARES underwater neutrino telescope, at a depth of 2475 m in the Mediterranean Sea, near Toulon, is taking data in its final configuration of 12 detection lines. Each line is equipped with 75 photomultipliers (PMT) housed in glass pressure spheres arranged in 25 triplets at depths between 100 and 450 m above the sea floor. The PMTs look down at 45 to have better sensitivity to the Cherenk...

We present the measurement of the the flux and angular distribution of atmospheric νµ using the MACRO detector. Three different event topologies are detected in two different energy ranges. High energy neutrinos (Eν ∼ 80 GeV) via the identification of upward throughgoing muons. Lower energy neutrinos (Eν ∼ 4 GeV) via the upgoing stopping and partially contained downgoing muons (ID+UGS), or via ...
متن کاملMeasurement of Atmospheric Neutrinos at the Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory consists of a 1 kiloton heavy water Cherenkov detector able to detect and reconstruct high-energy muons created from cosmic ray showers and atmospheric neutrino interactions. By measuring the flux of through-going muons as a function of zenith angle, the SNO experiment can distinguish between the oscillated and un-oscillated portion of the neutrino flux. This re...
متن کاملSkymap for atmospheric muons at TeV energies measured in deep-sea neutrino telescope ANTARES
Recently different experiments mention to have observed a large scale cosmic-ray anisotropy at TeV energies, e.g. Milagro, Tibet and SuperKamiokande. For these energies the cosmic-rays are expected to be nearly isotropic. Any measurements of cosmic-rays anisotropy could bring some information about propagation and origin of cosmic-rays. Though the primary aim of the ANTARES neutrino telescope i...
متن کاملResults from Super-kamiokande
The results from Super-Kamiokande on atmospheric neutrinos and solar neutrinos are presented. The contained event analysis of atmospheric neutrinos shows a small value of p/e ratio and a large asymmetry in the zenith angle distribution. A distortion of zenith angle distribution is observed in the upward-through-going muons resulting from atmospheric neutrino interactions in the rock surrounding...
