Contribution

This paper presents the first analysis results from ANTARES, demonstrating its capabilities and performance in neutrino detection and astrophysical searches.

Findings

Detector successfully discriminates upgoing neutrinos from atmospheric muons.

Data and simulation are in good agreement.

Initial results show potential for astrophysical source detection.

Abstract

ANTARES is the first undersea neutrino telescope. It is in its complete configuration since May 2008 at about 2.5 km below the sea surface close to Marseille. Data from 12 lines are being analyzed and are producing first results. Here we discuss first analysis results for 5 lines and 10 lines, and we also comment on the performance of the full detector. We show that the detector has capabilities for discriminating upgoing neutrino events from the much larger amount of downgoing atmospheric muons and that data and simulation are in good agreement. We then discuss the physics reach of the detector for what concerns point-like source and dark matter searches.
