Measurement of Atmospheric Neutrino Oscillations with PINGU — •Kai Krings, Stefan Coenders, Sebastian Euler, Markus Vehring, Marius Wallraff, and Christopher Wiebusch — III. Physikalisches Institut, RWTH Aachen, D-52056 Aachen
With IceCube’s low-energy extension DeepCore it is possible to study atmospheric neutrino oscillations in the energy range between 10 GeV and 100 GeV. Current analyses are sensitive to the first minimum of the survival probability of atmospheric muon neutrinos at about 25 GeV for vertically upgoing neutrinos. For the ’Precision IceCube Next Generation Upgrade’ (PINGU) it is planned to install additional strings with a denser spacing inside the DeepCore volume. By this, PINGU will lower the neutrino energy threshold to a few GeV. In this talk it is investigated how the accuracy of the measurement of the oscillation parameters θ23 and Δ m32 can be improved by PINGU with respect to DeepCore.
