Search for heavy neutral lepton production and decay with the IceCube Neutrino Observatory — •Leander Fischer for the IceCube collaboration — DESY Zeuthen

We investigate the ability of IceCube DeepCore to reconstruct low-energy (GeV) double-cascade topologies, which can be produced through Beyond Standard Model interactions. In particular, we consider Heavy Neutral Leptons (HNLs) in the mass range of 0.1-3 GeV that are produced from up-scattering of atmospheric tau-neutrinos. The sensitivity to HNL interactions, where the production and subsequent decay happen inside the detector volume, is investigated using 8 years of atmospheric data from IceCube DeepCore.
