“…Another approach to the high energy behavior of the neutrino cross section is to rely on a formalism that encodes the asymptotic behavior of the high energy cross section to preserve unitarity [93][94][95][96][97][98]. In a series of papers [93][94][95] Finally, a parameterization of the electromagnetic structure function F 2 determined from scattering data at HERA by Abramowicz et al [99,100] can be adapted to apply to the high energy neutrino cross section [97].…”

Ultra-high-energy neutrinos serve as messengers of some of the highest energy astrophysical environments. Given that neutrinos are neutral and only interact via weak interactions, neutrinos can emerge from sources, traverse astronomical distances, and point back to their origins. Their weak interactions require large target volumes for neutrino detection. Using the Earth as a neutrino converter, terrestrial, sub-orbital, and satellite-based instruments are able to detect signals of neutrino-induced extensive air showers. In this paper, we describe the software code nuPyProp that simulates tau neutrino and muon neutrino interactions in the Earth and predicts the spectrum of the τ-leptons and muons that emerge. The nuPyProp outputs are lookup tables of charged lepton exit probabilities and energies that can be used directly or as inputs to the nuSpaceSim code designed to simulate optical and radio signals from extensive air showers induced by the emerging charged leptons. We describe the inputs to the code, demonstrate its flexibility and show selected results for τ-lepton and muon exit probabilities and energy distributions. The nuPyProp code is open source, available on github.

“…The adaptation to neutrino scattering structure functions leads to the curve in Figure 5 labeled Block14. This same structure function F 2 can be translated to a dipole cross section (99,100), which in the dipole framework is used to evaluate the neutrino CC cross section labeled Argüelles15 in Figure 5 (98).…”

The cross sections for neutrino interactions with nucleons have been measured directly in accelerator experiments and through the zenith-angle and energy dependence of neutrino events at the IceCube Neutrino Observatory. Fluxes of high-energy neutrinos are produced at the Large Hadron Collider and by cosmic rays in the atmosphere. High-energy neutrinos also come from astrophysical and cosmic sources. The theory of neutrino interactions is reviewed. Current cross-section measurements and prospects for the future are discussed. The focus here is on neutrino interactions for energies larger than 1 TeV. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 73 is September 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…The authors in Ref. [34] presented the dipole cross section from an approximate form of the presumed dipole cross section convoluted with the perturbative photon wave function for virtual photon splitting into a color dipole with massless quarks. Some approximated analytical solutions in the color dipole model have been reported in recent years [35][36][37][38][39][40][41][42] with considerable phenomenological success.…”

We show that the geometric scaling of the dipole cross section can be explained using standard DGLAP perturbative evolution. The DGLAP-improved saturation model due to the Laplace transform method is considered at LO and NNLO approximations from the experimental data by relying on a Froissart-bounded parametrization of $$F_{2}(x,Q^{2})$$ F 2 ( x , Q 2 ) . These results are comparable with the Golec-Biernat–W$$\ddot{\mathrm {u}}$$ u ¨ sthoff (GBW) model in a wide kinematic region $$rQ_{s}$$ r Q s which takes into account charm mass. The successful description of $${\sigma }_{\mathrm {dip}}(x,r)/\sigma _{0}$$ σ dip ( x , r ) / σ 0 and $${\sigma }_{\mathrm {dip}}(rQ_{s})/\sigma _{0}$$ σ dip ( r Q s ) / σ 0 are presented.
