All-flavor search for a diffuse flux of cosmic neutrinos with 9 years of ANTARES data

Understand

The ANTARES detector is at present the most sensitive neutrino telescope in the Northern Hemisphere.

• The highly significant cosmic neutrino excess observed by the Antarctic IceCube detector can be studied with ANTARES, exploiting its complementing field of view, exposure, and lower energy threshold.
• Searches for an all-flavor diffuse neutrino signal, covering 9 years of ANTARES data taking, are presented in this letter.
• Upward-going events are used to reduce the atmospheric muon background.
