QCD dynamic effects in the neutrino absorption by the Earth’s interior at IceCube neutrino energies and above

Abstract

We investigate how the uncertainties in σνN due the different QCD dynamic models would modify the neutrino absorption while they travel across the Earth. We compare the predictions of models based on the solution of the linear DGLAP equations at small-x and large-Q2 with those which impose the Froissart bound at large energies, taking into account the unitarity effects in the neutrino - nucleon cross section. Our results indicate that the probability of absorption and the angular distribution of neutrino events are sensitive to the QCD dynamics at ultra high energies.
