Measurement of the high-energy all-flavor neutrino-nucleon cross section with IceCube

Abstract

The flux of high-energy neutrinos passing through the Earth is attenuated due to their interactions with matter. Their transmission probability is modulated by the neutrino interaction cross section and affects the arrival flux at the IceCube Neutrino Observatory, a cubic-kilometer neutrino detector embedded in the South Pole ice sheet. We present a measurement of the neutrino-nucleon cross section between 60 TeV-10 PeV using the high-energy starting events (HESE) sample from IceCube with 7.5 years of data.
