TL;DR
This study searches for relativistic magnetic monopoles using the ANTARES neutrino telescope, setting upper limits on their flux based on 116 days of data, and finds no significant monopole events.
Contribution
First search for relativistic magnetic monopoles with ANTARES, establishing flux upper limits and demonstrating the detector's capability for such searches.
Findings
No monopole events detected beyond background expectations.
Established 90% C.L. upper limits on monopole flux between 1.3E-17 and 8.9E-17 cm^-2 s^-1 sr^-1.
Data set of 116 days used for the analysis.
Abstract
Magnetic monopoles are predicted in various unified gauge models and could be produced at intermediate mass scales. Their detection in a neutrino telescope is facilitated by the large amount of light emitted compared to that from muons. This paper reports on a search for upgoing relativistic magnetic monopoles with the ANTARES neutrino telescope using a data set of 116 days of live time taken from December 2007 to December 2008. The one observed event is consistent with the expected atmospheric neutrino and muon background, leading to a 90% C.L. upper limit on the monopole flux between 1.3E-17 and 8.9E-17 cm-2.s-1.sr-1 for monopoles with velocity beta greater than 0.625.
