Computational and statistical aspects of neutrino mass ordering studies with very-large-volume neutrino telescopes — •Thomas Ehrhardt and Sebastian Böser for the IceCube collaboration — Institut für Physik, Universität Mainz

Very-large-volume neutrino telescopes (VLVnTs) have the potential to determine the neutrino mass ordering (NMO) via a measurement of the flux of atmospheric neutrinos in the GeV energy range. Their sensitivity is brought about by an asymmetry in the oscillation pattern of Earth-crossing neutrinos. In combination with flux and cross-section differences between neutrinos and anti-neutrinos, this results in a few-percent net imprint of the NMO on the measured spectra, which can only be resolved unambiguously with megaton-scale detectors. In this talk, we highlight some computational and statistical challenges emerging from the high-statistics nature of the experiment, and introduce a fast detector simulation framework in which they are addressed.
