【 摘 要 】

The PINGU (Precision IceCube Next Generation Upgrade) experiment is a proposed project that will probe the neutrino mass hierarchy by studying the energy and zenith spectra of atmospheric neutrinos. PINGU in a few years will collect a huge statistics (O(105events) and its sensitivity will be limited by systematics errors. In this work we discuss the impact of the shape systematics on the hierarchy determination.
