| Abstract: | The 1D2 and 3F3 diproton anomalies are studied in a framework of Faddeev πNN dynamics with ρ-exchange contribution. Two-body interactions in πN-P33, πN-P11, NN-3P2; and NN-3Si1 states are input. The pp-pp, pp-πd and πd-πd processes are treated in a unified way and the results are compared with partial wave analysis results of each process. The 1D2 and 3F3 diproton anomalies are qualitatively explained by the present models. The ρ-contributions are remarkable in the amplitudes of pp-pp and pp-πd processes from the pp-1D2 state. |
