| 摘 要： | 讨论了高能强子 -强子散射过程中的坡密子以及坡密子的 QCD内容 .认为坡密子有可能就是具有量子数 IG=0 + ,JPC=2 + +的张量胶子球 ξ( 2 2 30 ) .用雷其化胶子球模型计算了高能质子 -质子散射截面和坡密子 -核子的耦合参数 β.理论结果与实验的要求一致. The pomeron in high energy hadron hadron scattering as well as the QCD nature of the pomeron are discussed. We claimed that the pomeron may be the tenser glueball ξ(2 230) with quantum number I G =0 +, J PC =2 ++ . Under this reggeized glueball model the cross section of high energy proton proton scattering and the coupling parameter of the pomeron nucleon, β , are calculated. The theoretical results of the present model are in good agreement with experimental data.

| Abstract: | The pomeron in high energy hadron-hadron scattering as well as the QCD nature of the pomeron are discussed.We claimed that the pomeron may be the tenser glueball ξ(2 230) with quantum number IG ＝0+, JPC＝2++. Under thisreggeized glueball model the cross section of high energy proton-proton scattering and the coupling parameter of the pomeron-nucleon, β, are calculated. The theoretical results of the present model are in good agreement with experimental data. |
