Unified atmospheric neutrino passing fractions for large-scale neutrino telescopes

Understand

The atmospheric neutrino passing fraction, or self-veto, is defined as the probability for an atmospheric neutrino not to be accompanied by a detectable muon from the same cosmic-ray air shower.

• Building upon previous work, we propose a redefinition of the passing fractions by unifying the treatment for muon and electron neutrinos.
• Several approximations have also been removed.
• This enables performing detailed estimations of the uncertainties in the passing fractions from several inputs: muon losses, cosmic-ray spectrum, hadronic-interaction models and atmosphere-density profiles.
