首先强调了在高能强作用软(高强软)过程,特别是在强子散射总截面中,单由Pomeron(IP)交换就渐进地饱和了幺正性条件这件事的重要性.结合对Landshoff和Nachtmann的IP场论模型适当修改,提出了最大非微扰强作用反应假说.与此相关,认为IP由这种反应中得出的一对共轭色八重态胶团组成.通过对修改后的q-q弹性振幅虚部图形的物理内涵的考察,一方面预言了高强软过程中会产生组分胶子,胶球态是...

讨论高能双衍射硬产生过程.假定Pomeron(P)中以胶子分布为主且小x处有的行为后,计算了截面随能量的变化,比较了它们与单衍射(单个P交换)硬过程和非衍射Drell-Yan相应过程的截面随的变化.得出双衍射硬过程与单衍射时相似,在超高能(TeV以上)区截面基本上都是以(lnS)2增加,指出了这在实验中可能具有的意义.

指出Pomeron可以被看作为具有Regge轨道αp(t)=1.08+0.2GeV－2t的Regge化的胶子球.理论成功地预言了实验上观测到的质子一质子弹性散射的总截面.理论与实验的最好符合给出了张量胶子球到质子反质子道的衰变宽度为9±3MeV,其总宽度大于50MeV.并且排除了张量胶子球的自旋为4的可能性.
