摘要：

I overview our recent activity with the Argonne-Osaka dynamical coupled-channels (DCC) approach that provides a unified description of various electroweak meson productions on single nucleon and nucleus. First I discuss the DCC model of a single nucleon. The DCC model has been developed through a comprehensive analysis of pi N, gamma N -> pi N, eta N, K Lambda, K Sigma reaction data. The model has been further extended to finite Q(2) region by analyzing pion electroproduction data, and to neutrino-induced reactions using the PCAC relation. Next I discuss applications of the DCC model to electroweak meson productions on the deuteron. We consider impulse mechanism supplemented by final state interactions (FSI) due to NN and meson-nucleon rescatterings. Using this model, I discuss FSI corrections needed to extract gamma-neutron reaction observables from gamma d -> pi NN, and a novel method to extract eta N scattering length from gamma d -> eta pn. I also discuss FSI corrections on the existing neutrino-nucleon pion production data that had been extracted from neutrino-deuteron data.
