Latest results on atmospheric neutrino oscillations from IceCube/DeepCore

The IceCube Neutrino Observatory, located at the South Pole, is the world's largest neutrino detector. DeepCore, the low energy extension for IceCube, with a threshold of about ten GeV is well suited to study neutrino oscillations using neutrinos produced in the Earth's atmosphere and traveling distances as large as the Earth's diameter before being detected. Using these neutrinos DeepCore makes measurements of the neutrino oscillation parameters theta(23) and vertical bar Delta m(32)(2)vertical bar with precisions approaching that of dedicated experiments, and based on preliminary studies these results can still be further improved. These new studies as well as the current results obtained in DeepCore are discussed here.
