Background estimation for sub-relativistic particle searches with IceCube — •Jakob Böttcher, Christian Haack, Michael Handt, Timo Stürwald, Christopher Wiebusch, and Simon Ziercke for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University

The IceCube Neutrino Observatory is a multi-purpose detector with research programs encompassing neutrinos, muons, and more exotic particles, such as magnetic monopoles. These monopoles are predicted to catalyse proton decays and, depending on their mass, can propagate with sub-relativistic velocities. To find these slow particles, IceCube has a dedicated trigger that is sensitive to time scales a factor 1000 larger than the usual event duration. Since the expected rate of such particles is small, if existent, the estimation of background is crucial for such a search. Explicitly, the challenge lies in simulating correlated noise for the long time scales that have to be considered. We present an efficient way to generate and parametrize the background by reusing actual data from the detector.
