Signatures of sub-relativistic magnetic monopoles in IceCube — •Timo Stürwald, Jakob Böttcher, Christian Haack, Michael Handt, Jöran Stettner, Christopher Wiebusch, and Simon Zierke for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen

The IceCube Neutrino Observatory is a km3 scale Cherenkov light detector that also searches for signatures of particles beyond the standard model. Sub-relativistic magnetic monopoles may catalyze proton decay via the Rubakov-Callan effect. Icecube can detect the Cherenkov light induced by this process. However, the cross-section for this process is model dependent and ranges over several orders of magnitude. This results in diverse signatures of monopoles, slowly moving through the detector. Thus, it is important to find significant variables that characterize the signal with respect to background. In this talk, we present a new selection method based on machine learning.
