- 中文摘要: Low energy - interaction is studied in the Veneziano model. It is shown thatthe pure Veneziano model with p trayectory dominance can describe the I=o, J=0low energy behavior of the - system qualitatively. It predicts the existence ofE resonance which is considerably broader than the p resonance. The final stateinteraction effect characterized by two pion intermediate state is considered. It isconcluded that the correction is small but in the correct direction for the energyregion below E mass. In the a region it has the effect to produce a long shoulderwhich is favoured by the present experimental data.
