Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II
The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100GeV to 10TeV energy range. The zenith angle and energy distribution of these events can be used to search for various phenomenological sig...
