Neutrino telescopes in the Mediterranean
Dr. Thomas Eberl (Universität Erlangen)


The ANTARES detector, located 40 km off the French coast, is the largest deep-sea neutrino telescope in the Northern Hemisphere and takes data since 2008.
It consists of an array of 885 photomultipliers detecting the Cherenkov light induced by charged particles emitted in neutrino interactions in and around the detector.
The primary goal of ANTARES is to search for astrophysical neutrinos in the TeV to PeV energy range. This comprises generic searches for any diffuse cosmic neutrino flux as well as more specific searches for astrophysical sources such as Active Galactic Nuclei or Galactic sources.
The search program also includes multi-messenger analyses based on time and/or space coincidences with other cosmic probes.
The ANTARES observatory is also sensitive to a wide-range of other phenomena, from atmospheric neutrino oscillations to dark matter annihilation or possible exotics such as nuclearites and magnetic monopoles.

The KM3NeT collaboration currently constructs the next generation of neutrino telescopes in the Mediterranean. The ARCA array of telecopes is built off the coast of Sicily and will in its first phase investigate the diffuse cosmic neutrino signal recently discovered by IceCube. In its second phase it will be sensitive to the expected neutrino emission of mainly Galactic sources. The construction of the ORCA detector has started close to the ANTARES site in France. Its main goal will be the detection of GeV range atmospheric neutrinos and the determination of the neutrino mass ordering.

The talk will provide an overview of the technology and challenges of deep sea Cherenkov neutrino telescopes, present selected ANTARES results and will give an outlook on the discovery potential of the KM3NeT detectors.
