Search of BSM Particle STau in IceCube — •Jan-Henrik Schmidt-Dencker, Stephan Meighen-Berger, Christian Haack, and Elisa Resconi for the IceCube collaboration — Technische Universität München

The supersymmetric partner of the Tau lepton, the STau, appears in some models as the next-to lightest and therefore a long-lived particle. In this scenario its signature is a long-dim minimally ionizing track when travelling through the IceCube detector. The STau tracks, independent of their primary energy, seem like low energy muons for the detector and will appear as an excess on the muon tracks by atmospheric neutrinos. In our analysis we focus on the region around the horizon as we expect the ratio between STau signal and atmospheric muons to be best there. We then calculate the sensitivity to constrain the mass of the STau using the IceCube detector.
