Studies of the Reconstruction of Cascade-Like Events in PINGU — •Thomas Ehrhardt — Institut für Physik, Universität Mainz

PINGU (Precision IceCube Next Generation Upgrade) is the envisaged low-energy extension of the IceCube neutrino detector, located at the South Pole. With its high density of optical sensors, deployed at depths where the Antarctic ice is clearest, PINGU will be able to effectively detect neutrinos with energies above a few GeV. Precise reconstruction of neutrino zenith angles and energies are necessary for PINGU to reach its primary physics goal, the determination of the neutrino mass hierarchy. In this talk, the performance of a likelihood-based resolution estimator is examined, and its potential of improving PINGU's neutrino mass hierarchy sensitivity in the cascade channel is discussed.
