Abstract: (Physical Society of Japan)

A dynamical coupled-channels (DCC) model for neutrino-nucleon reactions in the resonance region is developed. The DCC model is an extension of what we have previously developed through an analysis of πN, γN → πN, ηN, KΛ, KΣ reaction data for W ≤ 2.1 GeV. In extending the DCC model, we analyze electron-induced reaction data for both proton and neutron targets to determine the vector form factors up to Q^2 ≤ 3.0 (GeV/c)^2. We derive axial current matrix elements in accordance with the Partially Conserved Axial Current (PCAC) relation to the πN interactions of the DCC model. We compare our calculated cross sections for neutrino-induced single-pion productions with available data, and find a reasonable agreement. We also calculate cross sections for the two-pion production in the resonance region, for the first time, with relevant resonance contributions and channel couplings taken into account. We compare the result with available two-pion production data.
