Search for magnetic monopoles with the complete ANTARES dataset Albert, A. ANTARES Collaboration, / Díaz García, Antonio Francisco Navas Concha, Sergio ANTARES telescope Magnetic monopoles Water Cherenkov detectors This study presents a search for magnetic monopoles using the full ANTARES dataset collected over 14 years (2008--2022). The interaction of monopoles with matter was modeled according to the Kazama, Yang and Goldhaber cross-section, and dedicated reconstruction strategies were applied to probe velocities both above and below the Cherenkov threshold. No signal consistent with monopoles was found. We derive 90% C.L. upper limits on the flux of relativistic monopoles at the level of 10−18 cm−2 s−1 sr−1, improving upon previous ANTARES results and confirming those obtained by IceCube and other neutrino telescopes. These results constitute the final contribution of ANTARES to the search for magnetic monopoles. 2025-11-11T11:07:08Z 2025-11-11T11:07:08Z 2026-02 journal article The ANTARES Collaboration. (2026).
