TeV-PeV neutrino-nucleon cross section measurement with 5 years of IceCube data

Understand

We present a novel analysis method for the determination of the neutrino-nucleon Deep Inelastic Scattering (DIS) cross section in the TeV - PeV energy range utilizing neutrino absorption by the Earth.

• We analyze five years of data collected with the complete IceCube detector from May 2011 to May 2016.
• This analysis focuses on electromagnetic and hadronic showers (cascades) mainly induced by electron and tau neutrinos.
• The applied event selection features high background rejection (< 10% background contamination below 60 TeV, background free above 60 TeV) of atmospheric muons and high signal efficiency (~ 80%).
