Abstract
The flux of high-energy neutrinos passing through the Earth is attenuated due
to their interactions with matter. The interaction rate is modulated by the
neutrino interaction cross section and affects the flux arriving at the IceCube
Neutrino Observatory, a cubic-kilometer neutrino detector embedded in the
Antarctic ice sheet. We present a measurement of the neutrino cross section
between 60 TeV and 10 PeV using the high-energy starting events (HESE) sample
from IceCube with 7.5 years of data. The result is binned in neutrino energy
and obtained using both Bayesian and frequentist statistics. We find it
compatible with predictions from the Standard Model. Flavor information is
explicitly included through updated morphology classifiers, proxies for the the
three neutrino flavors. This is the first such measurement to use the three
morphologies as observables and the first to account for neutrinos from tau
decay.
