PI-NN DYNAMICS IN PP-]PP, PP-]PI-D, AND PI-D-]PI-D PROCESSES BELOW 1 GEV

pp and pi d scattering and pp --> pi d reaction processes at incident proton laboratory energies T-L less than or equal to 1 GeV are studied in the framework of pi NN dynamics. For this purpose three-body calculations are performed with the pi N interaction in the P-11, P-33, S-11 and S-31 states and NN forces in the S-3(1)-D-3(1), S-1(0), and P-3(2) states. In addition, the backward-going pion contribution at the pi N Delta vertex, the pi N-rho N coupling, the heavy-meson exchanges in the NN --> NN driving term, and the effect of the off-shell structure in the pi N-rho N P-33 interaction are taken into account.
