Description

The IceCube Neutrino Observatory detects neutrinos at energies orders of magnitude higher than those accessible to current accelerator neutrinos and probes fundamental neutrino properties at energies otherwise not accessible. Above 40 TeV, neutrinos of astrophysical and atmospheric origin traveling through the Earth will be absorbed as they interact with nuclei, changing the zenith angle distribution of the neutrinos in the detector. The change in zenith distribution provides a sensitivity measure of the neutrino-nucleon cross section. In this analysis, we use upgoing muon neutrinos passing through IceCube to measure the neutrino cross section at energies above 40 TeV. This analysis uses 8 years of upgoing muon neutrino data, which provides an order of magnitude increase in statistics compared to previous publications in this energy range. We present the cross section measurement in three decade-wide energy bins, and compare to previous cross section results from IceCube observations.
