Abstract

It is shown that in ultrahigh-energy inelastic neutrino-nucleon(nucleus) scattering the cross sections for the boson-hadron(nucleus) reactions should exhibit geometric scaling on the single variable \ensuremathτ_A=Q²/Q_sat,A². The dependence on energy and atomic number of the charged/neutral current cross sections are encoded in the saturation momentum Q_sat,A. This fact allows an analytical computation of the neutrino scattering on nucleon/nucleus at high energies, providing a theoretical parameterization based on the scaling property.
