Improving the Sensitivity of Measurements in IceCube to Neutrino Oscillation Parameters — •Alexander Trettin for the IceCube collaboration — DESY, Zeuthen

One of the applications of the IceCube Neutrino Observatory is the measurement of the neutrino mass splittings and mixing angles using atmospheric neutrinos. These measurements use the DeepCore sub-array of IceCube, which has an energy threshold of just under 10 GeV. One of the algorithms used for directional reconstruction in neutrino oscillation studies relies on the arrival time pattern of minimally scattered photons. This talk presents a simple yet effective way to minimize the impact of scattering in ice and increase the efficiency of this approach. Discussed improvements are expected to result in about 10% increase of the sensitivity to oscillation parameters in future studies.
