Abstract
    Muons created by nm charged current (CC) interactions in the water surrounding the ANTARES neutrino telescopehave been almost exclusively used so far in searches for cosmic neutrino sources. Due to their long range, highlyenergetic muons inducing Cherenkov radiation in the water are reconstructed with dedicated algorithms that allowfor the determination of the parent neutrino direction with a median angular resolution of about 0°.4 for an E-2neutrino spectrum. In this paper, an algorithm optimized for accurate reconstruction of energy and direction ofshower events in the ANTARES detector is presented. Hadronic showers of electrically charged particles areproduced by the disintegration of the nucleus both in CC and neutral current interactions of neutrinos in water. Inaddition, electromagnetic showers result from the CC interactions of electron neutrinos while the decay of a taulepton produced in nt CC interactions will, in most cases, lead to either a hadronic or an electromagnetic shower. Ashower can be approximated as a point source of photons. With the presented method, the shower position isreconstructed with a precision of about 1 m; the neutrino direction is reconstructed with a median angularresolution between 2° and 3° in the energy range of 1–1000 TeV. In this energy interval, the uncertainty on thereconstructed neutrino energy is about 5%–10%. The increase in the detector sensitivity due to the use of additionalinformation from shower events in the searches for a cosmic neutrino flux is also presented.
