Search for Magnetic Monopoles with the Full ANTARES Neutrino Telescope Dataset

Key Points

No magnetic monopole events were detected in the ANTARES dataset, leading to stringent upper limits on their flux.
Upper limits established include $5.6 \times 10^{-19}~\text{cm}^{-2}~\text{s}^{-1}~\text{sr}^{-1}$ for ultra-relativistic monopoles.
The analysis was based on 14 years of data, using a model based on the Kasama, Yang, and Goldhaber cross-section.
These findings indicate a need for further exploration of magnetic monopoles and their properties in particle physics.

Abstract

This study presents a novel search for magnetic monopoles using data collected over a 14-year period (2008–2022) by the ANTARES neutrino telescope. The interaction of magnetic monopoles with matter was modeled using the Kasama, Yang, and Goldhaber cross-section. Upper limits on the flux of magnetic monopoles were derived for velocities both above and below the Cherenkov threshold. No events consistent with the passage of magnetic monopoles were detected, allowing to set an upper flux limit of 5. 6 10^-19~cm^-2~s^-1~sr^-1 for ultra-relativistic monopoles and 3. 4 10^-18~cm^-2~s^-1~sr^-1 for slow monopoles.
