Description

IceCube is a cubic kilometer neutrino telescope located at the geographic South Pole. Although primarily designed for the detection of cosmic neutrinos, the detector is well suited for measurements of the atmospheric muon neutrino energy spectrum. We present the first measurement of the atmospheric neutrino energy spectrum obtained in its full 86-string configuration. The analysis was carried out using dedicated machine learning algorithms for the selection of neutrino candidates. The spectrum was obtained by applying regularized unfolding as implemented in the unfolding software TRUEE. An additional component due a diffuse flux of high energy astrophysical neutrinos has been observed in addition to the flux of atmospheric neutrinos.
