Neutrino nucleus reactions at high energies — •Olga Lalakulich, Kai Gallmeister, Tina Leitner, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

Modern long baseline neutrino experiments, aiming at measuring the neutrino oscillation parameters, base their analysis on models for neutrino-nucleus interactions. Theoretical understanding of nuclear effects is essential for the interpretation of the experimental data. Within the Giessen Boltzmann–Uehling–Uhlenberck (GiBUU) coupled channel transport model we examine neutrino and antineutrino interactions with nuclei. The neutrino first interacts with a bound nucleon, moving within the Fermi sphere in a hadronic potential. After the initial interaction, the outgoing hadrons undergo complex hadronic final state interactions with all kinds of coupled channel effects included. Calculations of the total cross sections are compared with the recent data of the MINOS and NOMAD Collaborations for neutrino beam energies from 4 to 45 GeV. Predictions for kinetic energy distributions of the outgoing nucleons, pions and kaons, as well as for other differential cross sections, are made for the Minerνa experiment.
