Testing the Neutrino Mass Ordering Using 4 Years of IceCube/DeepCore Data — •Martin Leuermann, Marius Wallraff, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University, Germany

The measurement of the Neutrino Mass Ordering (NMO), i.e. the ordering of the three neutrino mass eigenstates, is one of the major goals of many future neutrino experiments. One strategy is to measure matter effects in the oscillation pattern of atmospheric neutrinos as e.g. proposed for the PINGU extension of the IceCube Neutrino Observatory. Already, the currently running IceCube/Deepcore detector can explore this type of measurement -- however, with lower significance.

We present a three dimensional likelihood analysis based on 4 years of IceCube data searching for indications of the NMO with a data sample reaching to energies below 10GeV and improved reconstruction techniques.
