A Hamiltonian for π, N, and Δ is constructed from meson-exchange mechanisms. The NN interaction in the model is directly derived from the Paris potential. Good fits to pp scattering data up to 1 GeV, including the "resonant" D21 and F33 partial waves, have been obtained when a πNΔ interaction is introduced in a dynamical three-body approach. The model can be used for a many-body study of Δ-nucleus dynamics.
