Results from Measuring the Neutrino Mass Ordering with IceCube DeepCore — •Martin Leuermann, Martin Rongen, Marius Wallraff, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, Otto-Blumenthal-Str., 52074 Aachen

The measurement of the Neutrino Mass Ordering (NMO), i.e. the ordering of the neutrino mass eigenstates, is one of the outstanding questions in Neutrino Physics which is in the focus of many experiments. One experimental strategy is to measure matter effects in the oscillation pattern of atmospheric neutrinos, while propagating through Earth, as proposed for PINGU as part of the IceCube-Gen2 Neutrino Observatory. With three years of data from the currently running IceCube Deepcore detector, we have explored this type of measurement, resembling the methods as proposed for PINGU. However, due to the higher energy threshold, the sensitivity is lower. In this talk, we present the results of this first measurement.
