AbstractAbstract
[en] 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 "c"i"r"c"l"e for shower energies below 100 TeV. Applying this algorithm to 6 years of data taken with the ANTARES detector, 8 events with reconstructed shower energies above 10 TeV 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 E"2 . Φ"9"0"% = 4.9 . 10"-"8 GeV . cm"-"2 . s"-"1 . sr"-"1 is set, applicable to the energy range from 23 TeV to 7.8 PeV, assuming an unbroken E"-"2 spectrum and neutrino flavour equipartition at Earth.
