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

説明

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 P 11, P 33, S 11 and S 31 states and NN forces in the 3 S 1 -3 D 1, 1 S 0, and 3 P 2 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 P 33 interaction are taken into account.
