Abstract

The freely distributed software packages Nudisxs and NuPropagator are presented. The nudisxs package is designed to calculate differential and total cross sections of deep inelastic interactions of neutrinos with nucleons during the exchange of \(W\) and \(Z\) bosons. The program NuPropagator, which implements the \(\mathcal{Z}\) -factor method, is used to calculate the change in neutrino flux as it propagates through matter. An analysis of the contribution of the phase space region where there are no experimental data on parton distributions to the value of the deep inelastic interaction cross sections and to the formation of neutrino flows has been carried out. In addition, the preliminary results of studies of the neutrino tomography sensitivity methods to the density distribution inside the Earth are presented.
