Atmospheric Neutrino Oscillations with DeepCore

: IceCube DeepCore can study atmospheric neutrino oscillations through a combination of its low energy reach,as low as about 10 GeV, and its unprecedented statistical sample, of about 150,000 triggered atmospheric muon neutrinosper year. With the diameter of the earth as a baseline, the muon neutrino disappearance minimum and tau neutrinoappearance maximum are expected at about 25 GeV, which is considerably lower energy than typical IceCube neutrinoevents, but higher than the energies at which accelerator-based experiments have detected oscillations. νµ disappearanceand ντ appearance from neutrino oscillation can be measured in IceCube DeepCore. We present here the status of thenewly developed low energy reconstruction algorithms, the expected experimental signatures, and the proposed approachfor such neutrino oscillation measurements
