KM3-230213A: The ultra-high-energy neutrino detected in KM3NeT

The detection by the KM3NeT neutrino telescope of the ultra-high-energy event KM3-230213A is a milestone in neutrino astrophysics. With an energy estimated of about 220 PeV, it is the most energetic neutrino observed to date, challenging the current understanding of the cosmic spectrum. Its observation opens the question of its astrophysical origin. In this talk, details on the KM3-230213A detection and observed signature will be presented, describing the detection technique and significance assessment. Possible astrophysical sources, including extragalactic and cosmogenic origins, will be discussed.
