Performance of reconstruction algorithms for PINGU

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 1 GeV 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.
