πNN Dynamics in pp → pp, pp → πd and πd → πd Processes Below 1 GeV

Abstract

pp and πd scattering and pp →πd reaction processes at incident proton laboratory energies T L ≤ 1 GeV are studied in the framework of πNN dynamics. For this purpose three-body calculations are performed with the πN interaction in the P11, P33, S11 and S31 states and NN forces in the 3S1 -3D1, 1S0, and 3P2 states. In addition, the backward-going pion contribution at the πNΔ vertex, the πN-ρN coupling, the heavy-meson exchanges in the NN → NN driving term, and the effect of the off-shell structure in the πN-ρN P33 interaction are taken into account.
