Search for Magnetic Monopoles with the Complete ANTARES Dataset

TL;DR

This paper reports a comprehensive 14-year search for magnetic monopoles using the ANTARES neutrino telescope, setting new upper flux limits and improving constraints on their possible existence.

Contribution

It introduces a novel analysis of ANTARES data for magnetic monopoles, including modeling their interactions and establishing upper flux limits across different velocities.

Findings

No magnetic monopoles detected in the dataset.

Upper flux limit for relativistic monopoles set at ~10^{-18} cm^{-2} s^{-1} sr^{-1}.

Constraints improve previous bounds on monopole flux.

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 according to Kazama, Yang, and Goldhaber cross-section. Upper limits on the flux of magnetic monopoles are obtained for velocities both above and below the Cherenkov threshold. No events consistent with the passage of magnetic monopoles were detected, enabling the setting of an upper flux limit for relativistic magnetic monopoles of the order of $10^{-18} \mathrm{cm}^{-2} \mathrm{s}^{-1} \mathrm{sr}^{-1}$.
