Description
Deep inelastic scattering on nucleons is the main process of interaction of high-energy neutrinos with matter. The corresponding cross sections are measured, for example, in the IceCube experiment on the basis of the dependence of the neutrino flux registered in the range 60 TeV - 10 PeV on the direction of its arrival in the detector [1]. This provides a unique opportunity to study the effects of physics beyond the Standard Model at high and ultrahigh neutrino energies. In particular, the search for the electromagnetic properties of neutrinos is of interest [2]. We have taken into account the contribution of neutrino charge and magnetic formfactors in the theoretical formalism of the process of deep inelastic neutrino scattering on the proton. In addition, we obtained expressions for the differential cross sections, which can be used to analyze and interpret the experimental data on deep inelastic neutrino scattering on nucleons in order to find the electromagnetic properties of neutrinos.
