| Résumé : | The detection of astrophysical sources of high energy neutrinos is one of the main motivations for building a neutrino telescope. The ANTARES telescope is being deployed in the Mediterranean Sea. The detector will consist in a tridimensional array of photomultipliers (PMTs) that will detect the Cherenkov light induced by the muons produced in neutrino interactions. Since the neutrino fluxes from point-like sources are expected to be small, it is of the utmost importance to take advantage of the ANTARES accurate pointing power (angular resolution less than 0.3 degrees for E greater than 10 TeV) to disentangle a possible signal from the unavoidable atmospheric neutrino background. In order to distinguish an excess of neutrino events from the background, several search algorithms have been developed within the ANTARES collaboration. Some of them perform binned searches of clusters, some others use likelihood maximization techniques and recently a method based on the well known Expectation- Maximization clustering algorithm has been devised. In this contribution, these different methods are reviewed and their discovery potential using the ANTARES neutrino telescope are presented. |
