Charged current neutrino-nucleus interactions at intermediate energies

We have developed a model to describe the interactions of neutrinos with nucleons and nuclei, focusing on the region of the quasielastic and Δ(1232) peaks. We describe neutrino-nucleon collisions with a fully relativistic formalism that incorporates state-of-the-art parametrizations of the form factors for both the nucleon and the N-Δ transition. The model has then been extended to finite nuclei, taking into account nuclear effects such as Fermi motion, Pauli blocking (both within the local density approximation), nuclear binding and final-state interactions. The in-medium modification of the {Δ} resonance because of Pauli blocking and collisional broadening have also been included. Final-state interactions are implemented by means of the Boltzmann-Uehling-Uhlenbeck (BUU) coupled-channel transport model. Results for charged current inclusive cross sections and exclusive channels as pion production and nucleon knockout are presented and discussed.
