Search of an ultra high energy neutrino diffuse flux with ANTARES telescope
The ANTARES high-energy neutrino telescope is a three-dimensional array of photomultipliers distributed over 12 lines, installed on the seabed in the Mediterranean Sea. The detector has been operated in partial configurations since March 2006 and the deployment was completed in May 2008. The main go...

The ANTARES high-energy neutrino telescope is a three-dimensional array of photomultipliers distributed over 12 lines, installed on the seabed in the Mediterranean Sea. The detector has been operated in partial configurations since March 2006 and the deployment was completed in May 2008. The main goal of the experiment is the search for high-energy neutrinos from astrophysical sources. A neutrino telescope in the Northern hemisphere includes the Galactic Center in its field of view and it can be seen as complement to the IceCube Antarctic telescope. The detector is optimized for the detection of muon neutrinos, since at energies above 1 TeV muons resulting from charged current interactions can travel kilometers and are almost collinear with the parent neutrinos. Ultra high energy neutrinos can have different origins: they could be created during the interaction of high energetic cosmic rays with the CMB or cosmological phenomena such as supernova remnants or AGNs. There are other possible sources due to new theories in the field of physics beyond the Standard Model. In my third year of PhD, I have performed the search for ultra high energy (in the energetic range of 100 PeV-10 EeV) extraterrestrial muon neutrinos from unresolved sources.
