PINGU Status Report — •Lukas Schulte for the IceCube collaboration — Physikalisches Institut, Universität Bonn

The Precision IceCube Next Generation Upgrade (PINGU) is planned as an infill to the IceCube array at the geographic South Pole. Every year, PINGU will record several ten thousands of atmospheric neutrinos with energies above 3 GeV.

With these unprecedented statistics, current simulations show that PINGU will be able to provide a 3 σ measurement of the neutrino mass hierarchy after five years of livetime. Also, PINGU will make precision measurements of the neutrino oscillation parameters ϑ₂₃ and Δ m₃₁² and set the World’s most stringent limits on spin-dependent dark matter interactions for low WIMP masses.

The current status of the PINGU project will be reported, with special emphasis on the sensitivity estimate of the neutrino mass hierarchy measurement.
