A novel algorithm to reconstruct neutrino-induced particle showers within the ANTARES neutrino telescope is presented. The method achieves a median angular resolution of 6◦ for shower energies below 100TeV. Applying this algorithm to 6 years of data taken with theANTARES detector, 8 events with reconstructed shower energies above 10TeV are observed. This is consistent with the expectation of about 5 events from atmospheric backgrounds, but also compatible with diffuse astrophysical flux measurements by the IceCube collaboration, from which 2–4 additional events are expected. A 90% C.L. upper limit on the diffuse astrophysical neutrino flux with a value per neutrino flavour of E2 ·90% = 4.9 · 10−8 GeV · cm−2 · s−1 · sr−1 is set, applicable to the energy range from 23TeV to 7.8PeV, assuming an unbroken E−2 spectrum and neutrino flavour equipartition at Earth.

Abstract

A novel algorithm to reconstruct neutrino-induced particle showers within the ANTARES neutrino telescope is presented. The method achieves a median angular resolution of 6◦ for shower energies below 100TeV. Applying this algorithm to 6 years of data taken with theANTARES detector, 8 events with reconstructed shower energies above 10TeV are observed. This is consistent with the expectation of about 5 events from atmospheric backgrounds, but also compatible with diffuse astrophysical flux measurements by the IceCube collaboration, from which 2–4 additional events are expected. A 90% C.L. upper limit on the diffuse astrophysical neutrino flux with a value per neutrino flavour of E2 ·90% = 4.9 · 10−8 GeV · cm−2 · s−1 · sr−1 is set, applicable to the energy range from 23TeV to 7.8PeV, assuming an unbroken E−2 spectrum and neutrino flavour equipartition at Earth.
