Search for Relativistic Magnetic Monopoles with the ANTARES Neutrino Telescope

leave a comment »

The ANTARES 90 % C.L. upper limit on an upgoing magnetic monopole flux for relativistic velocities 0.625 ≤ β ≤ 0.995 obtained in this analysis, compared to the theoretical Parker bound , the published upper limits obtained by MACRO for an isotropic flux of monopoles as well as the upper limits from Baikal and AMANDA for upgoing monopoles

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…..
