Abstract
An updated set of (anti)neutrino-nucleon charged and neutral current cross sections at $3~{\rm GeV} \lesssim E_\nu \lesssim 100~{\rm GeV}$ is presented. These cross sections are of particular interest for the detector optimization and data processing and interpretation in the future Megaton-scale experiments like PINGU, ORCA, and Hyper-Kamiokande. Finite masses of charged leptons and target mass corrections in exclusive and deep inelastic $(\bar\nu)\nu N$ interactions are taken into account. A new set of QCD NNLO parton density functions, the ABMP15, is used for calculation of the DIS cross sections. The sensitivity of the cross sections to phenomenological parameters and to extrapolations of the nucleon structure functions to small $x$ and $Q^2$ is studied. An agreement within the uncertainties of our calculations with experimental data is demonstrated.
Highlights
Future Megaton-scale neutrino detectors, such as PINGU, ORCA, and Hyper-Kamiokande can be used for determination of the neutrino mass hierarchy (NMH) with atmospheric neutrinos
We focus on the latter with an emphasis on the energy range Eν 3 GeV and present a self-consistent set of theoretical models and phenomenological parameters allowing us to describe the major contributions to the total νN and νN cross sections at these energies
We presented a comprehensive set of the total cross sections for the neutrino and antineutrino scattering off protons and neutrons at energies most important for the future experiments with Mton-scale neutrino detectors
Summary
Future Megaton-scale neutrino detectors, such as PINGU, ORCA, and Hyper-Kamiokande can be used for determination of the neutrino mass hierarchy (NMH) with atmospheric neutrinos. For the proper interpretation of the data, the accurate predictions of the atmospheric neutrino fluxes have to be paired with the reliable knowledge of the (anti)neutrinonucleon cross sections. We focus on the latter with an emphasis on the energy range Eν 3 GeV and present a self-consistent set of theoretical models and phenomenological parameters allowing us to describe the major contributions to the total νN and νN cross sections at these energies. The results of the present study may be included in future upgrade of the MC generator ANIS [1] in order to extend its validity to lower energies and improve the predictions for high and ultra-high energies.
