Neutrino Oscillation Measurements with IceCube

Understand

We present preliminary results for a neutrino oscillation analysis in progress on data collected with the IceCube 22-string detector during 2007 and 2008.

• The goal of this analysis is to measure muon neutrino disappearance as a function of energy for a constant baseline length of the diameter of the Earth by studying vertically up-going muon neutrinos.
• At this baseline disappearance effects are expected to become sizable at neutrino energies below 100 GeV.
• This energy range has not been previously explored with IceCube, however due to IceCube's vertical geometry there is some sensitivity for this specific class of events.
