Neutrino physics with IceCube

The IceCube Neutrino Observatory is an ice Cherenkov detector under construction at the South Pole, Antarctica. When completed, the physical volume of the detector will be approximately one km³. The Observatory will be sensitive to a number of topics in fundamental neutrino physics, such as neutrino oscillations and decay, by virtue of its ability to distinguish neutrino flavours over a wide range of neutrino energies. We present the status of the construction of the Observatory, some recent analysis results, a brief discussion of its sensitivity to fundamental neutrino parameters and planning currently underway for low and high energy extensions to the baseline array.
