Atmospheric neutrino oscillations with PINGU

Abstract

Measurements of atmospheric, solar, reactor and accelerator neutrinos (see e.g. [1, 2, 3, 4]) have shown that neutrinos undergo flavour-changing oscillations and hence have mass. The cubic-kilometre neutrino detector IceCube [5] with its more densely instrumented inner region DeepCore [6] has studied oscillations of atmospheric neutrinos at energies above ∼ 10 GeV [7, 8, 9]. The Precision IceCube Next Generation Upgrade (PINGU) [10] is a proposed extension of IceCube with the goal to perform precise measurements of atmospheric neutrino oscillations down to a few GeV and to determine the neutrino mass hierarchy (NMH).
