Search for magnetic monopoles, utilizing luminescence light, with the IceCube detector* — •Frederik Lauber for the IceCube collaboration — Bergische Universität Wuppertal

Magnetic monopoles are hypothetical particles predicted by many Beyond the Standard Model theories. They are carriers of single elementary magnetic charge. This work considers Intermediate Mass Monopoles which have been created shortly after the Big Bang. No recent search exists for the low relativistic range (0.1 − 0.5 c) because of the predominant usage of Cherenkov light as a detection mechanism in current experiments. No Cherenkov light is produced in the considered velocity range. Still, highly ionizing particles such as magnetic monopoles produce luminescence light in water and ice. To detect luminescence light, a high effective detection volume, as provided by the IceCube detector, with a high sensitivity to light is needed.

An ongoing search in the low relativistic range, utilizing luminescence light for the first time as a detection method with the IceCube detector, is outlined. Signal simulation will be shown as well as a first comparison between data, taken with the new monopole filter of the IceCube detector, and background simulation. The first separating variables used in the search will be presented.
