Possibility of parametrization of atmospheric muon angular flux using underwater data
نویسنده
چکیده
We present the formula for angular distribution of integral flux of conventional (π, K) muons deep under water taking into account the sphericity of the atmosphere and fluctuations of muon energy losses. The accuracy of this formula for various sea level muon spectra is discussed. The possibility of reconstructing two parameters of sea level spectrum by fitting measured underwater angular intensity is shown for Baikal Neutrino Telescope NT–36 experimental data.

Parametrization of the Cosmic Muon Flux for the Generator CMSCGEN
The cosmic muon generator CMSCGEN is based on a parametrization of the differential muon flux at ground level, as obtained from the air shower simulation program CORSIKA. We present the underlying ansatz for this parameterization and provide an approximation of the momentum and angular distributions in terms of simple polynomials, in the momentum range 3− 3000GeV.
متن کاملAtmospheric neutrino oscillations with the MACRO detector
After a short overview of the MACRO detector, located at the Gran Sasso Laboratory, I shall present and discuss the results on atmospheric muon neutrino oscillations, concerning low (〈Eν〉 ∼ 4 GeV) and high (〈Eν〉 ∼ 50 GeV) energy data. Using the Multiple Coulomb Scattering of muons inside the lower part of the detector, estimates of the neutrino energy were made event by event for the high energ...
متن کاملCosmic Ray Muon Physics
We present a review of atmospheric and underground muon flux measurements. The relevance of these data for the atmospheric neutrino flux computation is emphasized. Possible sources of systematic errors in the measurements are discussed, focusing on the sea level muon data. Underground muon data are also reported.
متن کاملZenith distribution and flux of atmospheric muons measured with the 5-line ANTARES detector
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 previou...
متن کامل5 A parameterisation of single and multiple muons in the deep water or ice
Atmospheric muons play an important role in underwater/ice neutrino detectors. In this paper, a parameterisation of the flux of single and multiple muon events, their lateral distribution and of their energy spectrum is presented. The kinematics parameters were modelled starting from a full Monte Carlo simulation of the interaction of primary cosmic rays with atmospheric nuclei; secondary muons...
