Measurement of atmospheric neutrino oscillations with the ANTARES neutrino telescope


Abstract:

The data taken with the ANTARES neutrino telescope from 2007 to 2010, a total live time of 863 days, are used to measure the oscillation parameters of atmospheric neutrinos. Muon tracks are reconstructed with energies as low as 20 GeV. Neutrino oscillations will cause a suppression of vertical upgoing muon neutrinos of such energies crossing the Earth. The parameters determining the oscillation of atmospheric neutrinos are extracted by fitting the event rate as a function of the ratio of the estimated neutrino energy and reconstructed flight path through the Earth. Measurement contours of the oscillation parameters in a two-flavour approximation are derived. Assuming maximal mixing, a mass difference of δm<inf>32</inf><sup>2</sup>=(3.1±0.9){dot operator}10<sup>-3</sup>eV<sup>2</sup> is obtained, in good agreement with the world average value. © 2012 Elsevier B.V.
