Neutrino-nucleus interactions in a hadronic transport model — •Tina Leitner and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen
The interest in neutrino-nucleus reactions is mainly driven by the discovery of neutrino oscillations. The experimental analyses have to rely on models for the neutrino-nucleus interaction to extract the oscillation parameters from the observed particle yields. In-medium modifications and, in particular, final-state interactions inside the target nucleus modify considerably the measured distributions. Thus, the theoretical understanding of nuclear effects is essential for the interpretation of neutrino oscillations.
These effects are investigated using the GiBUU transport model  which will be presented in this talk. In the first step, the neutrino interacts with a bound nucleon. This demands a good description of both, the elementary vertex and the in-medium-modifications. In the second step, the outcome of this initial reaction undergoes complex hadronic final-state interactions with all kinds of coupled-channel effects included. This talk discusses results for inclusive neutrino scattering, neutrino-induced pion production and nucleon knockout. Furthermore, the model is applied to recent experiments and questions relevant for oscillation measurements.
