IceCube-Gen2 and PINGU

IceCube-Gen2 collaboration is the next generation collaboration to focus on extending low and high energy physics of the IceCube Neutrino Observatory, Antarctica. Especially, PINGU (Precision IceCube Next Generation Upgrade) is the low energy extension of IceCube to detect the atmospheric neutrino oscillation below 10 GeV. The IceCube detector is a large array of DOMs (digital optical modules, each unit includes one PMT and an electronics and a calibration system), located ~1.5km under the south pole ice, and spans 1km2 to cover 1 giga ton ice as a target material of interactions. The main goal of IceCube is to detect ultra high energy neutrinos. Recently the first astrophysical neutrinos were observed (2013, http://icecube.wisc.edu/news/view/171). PINGU covers the central region of the IceCube detector (inside of the DeepCore) with higher density DOM arrays to detect lower energy neutrinos. The goal of PINGU is to determine neutrino mass hierarchy - one of the biggest questions of current particle physics - from atmospheric neutrino measurement.

Queen Mary has expertise on neutrino interaction physics, and we contribute to improve the neutrino interaction models, and we also estimate systematic errors related to neutrino interaction uncertainties on the neutrino mass hierarchy measurement in PINGU. On top of these, using existing data from the IceCube detector, we try to measure the flux-integrated neutrino cross section.
