IceCube Upgrade: ν-oscillations' high-statistics era

The IceCube Neutrino Observatory is a gigaton Cherenkov detector embedded within the Antarctic ice sheet. Earth-crossing atmospheric neutrinos provide IceCube with access to a unique combination of oscillation channels which include tau neutrino appearance. By deploying seven additional columns of new sensors at ten times higher density than the rest of IceCube, the Upgrade is expected to provide world-leading sensitivity to flavour oscillations through its unprecedented low-energy capabilities. This work presents sensitivity projections for standard atmospheric oscillations measurements enabled by the IceCube Upgrade.
