A reconstruction method for neutrino induced muon tracks taking into account the apriori knowledge of the neutrino source

Abstract

Gamma ray earthbound and satellite experiments have discovered, over the last years, many galactic and extra-galactic gamma ray sources. The detection of astrophysical neutrinos emitted by the same sources would imply that these astrophysical objects are charged cosmic ray accelerators and help to resolve the enigma of the origin of cosmic rays. A very large volume neutrino telescope might be able to detect these potential neutrino emitters. The apriori known direction of the neutrino source can be used to effectively suppress the ${}^{40}K$ optical background and increase significantly the tracking efficiency through causality filters. We report on advancing filtering and prefit techniques using the known neutrino source direction and first results are presented.
