Quest for neutrinos in the Mediterranean Sea

Neutrinos. Elusive messengers from the most violent and energetic phenomena in the cosmos. Travel across the Universe almost entirely undisturbed, carrying pristine information from their sources. Over more than a decade of operation, the ANTARES detector, the first undersea neutrino telescope, opened this new observational window from the depths of the Mediterranean before its decommissioning in 2022. Its legacy now continues and expands with KM3NeT, a next-generation observatory under construction at two deep-sea sites. At the Toulon site in France, KM3NeT ORCA is dedicated to precision measurements of atmospheric neutrinos and the exploration of fundamental oscillation parameters, while KM3NeT ARCA, deployed off the coast of Sicily, is designed to reveal high-energy cosmic neutrinos originating from powerful extragalactic accelerators.This seminar will revisit the scientific achievements of ANTARES. From the establishment of stringent limits on diffuse astrophysical fluxes and targeted searches for point-like sources, to its rich multi-messenger program. The first detections from KM3NeT are already signaling a new era: notably, the observation of KM3-230213A, the most energetic neutrino candidate ever recorded with a reconstructed muon energy near 120 PeV. Its characteristics suggest an origin in an extreme cosmic accelerator. Perhaps even a first glimpse of a cosmogenic neutrino. Looking ahead, KM3NeT promises to combine unprecedented precision in oscillation physics with the power to uncover the most energetic neutrino sources in the Universe. Together, ORCA and ARCA will probe the interface between particle physics and high-energy astrophysics, offering new insights into the mechanisms that govern both the smallest and the most colossal scales of the cosmos.
