Performance of reconstruction algorithms for PINGU — Alexander Kappes1,3, Sirin Odrowski2, Elisa Resconi2, and •Rezo Shanidze3 — 1Institut für Physik, Humboldt-Universität zu Berlin, D-12489 Berlin — 2Technische Universität München, D-85748 Garching — 3DESY, D-15738 Zeuthen
The planned PINGU upgrade of the IceCube detector, a 1 km3 neutrino telescope in the ice beneath the South Pole, aims at lowering the detector’s energy threshold to about 1GeV neutrino energies. The main goal is to render the detector sensitive to the neutrino mass hierarchy which manifests through matter effects in the oscillation pattern of atmospheric neutrinos. Key to achieving this goal is the performance of the neutrino reconstruction both in direction and energy. The talk presents a description of the topology of the events, the requirements on the reconstruction and various approaches that have been studied to achieve these requirements.
