Transport study of charged current interactions in neutrino-nucleus reactions

Within a dynamical transport approach we investigate charged current interactions in neutrino-nucleus reactions for neutrino energies of 0.3-1.5 GeV with particular emphasis on resonant pion production channels via the Δ33(1232) resonance. The final-state-interactions of the resonance as well as of the emitted pions are calculated explicitly for 12C and 56Fe nuclei and show a dominance of pion suppression at momenta pπ>0.2GeV/c. A comparison to integrated π+ spectra for νμ+C12 reactions with the available (preliminary) data demonstrates a reasonable agreement.
