First results from the ANTARES neutrino telescope
Th. Eberl (for the ANTARES collaboration)

TL;DR
The ANTARES neutrino telescope, operating in the deep sea, has provided initial measurements of atmospheric muon flux, set limits on cosmic neutrino flux, and conducted searches for point sources and gamma-ray blazars, with no significant signals detected.
Contribution
This paper presents the first results from ANTARES, including atmospheric muon flux measurement, limits on diffuse cosmic neutrino flux, and initial point source searches, demonstrating its capabilities in neutrino astronomy.
Findings
Good agreement with previous atmospheric muon flux measurements
Set limits on diffuse cosmic neutrino flux in the multi-TeV to PeV range
No significant neutrino signals detected from point sources or blazars
Abstract
The ANTARES detector is the most sensitive neutrino telescope observing the southern sky and the world's first particle detector operating in the deep sea. It is installed in the Mediterranean Sea at a depth of 2475 m. As an example of early results, the determination of the atmospheric muon flux is discussed and a good agreement with previous measurements is found. Furthermore, the results of a search for high-energy events in excess of the atmospheric neutrino flux are reported and significant limits are set on the diffuse cosmic neutrino flux in the multi-TeV to PeV energy range. Using data from more than 800 days of effective data taking, partly during the construction phase, a first analysis searching for point-like excesses in the neutrino sky distribution has been performed. The resulting sensitivity of ANTARES is reported and compared to measurements of other detectors. A method…
