Pomeron的结构和胶球的强生机制
Structure of the Pomeron and the Mechanism for Strong-Production of the Glueball
【摘要】 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 ,胶球态是由两个对撞的组分胶子熔合所形成 .另一方面 ,通过这里的色胶团单圈图与Gell mann Zweig的介子散射时夸克图的对应 ,论证了IP与胶球态之间存在着Regge极点型的二元性关系
【Abstract】 In this paper we first emphasize the importance of the Pomeron (IP) for its asymptotically saturation of the unitarity condition alone. After proper modified the field theory model for IP developed by Landshoff and Nochtmann,we argue that the exchange of IP in high energy h-h′ scattering embodies the hypothesis of the maximum non-perturbative strong interaction reaction (MNSIR) in which a constituent quark converts into a current quark and emits a color octet nonperturbative glue. We think the IP is composed from the conjugated pair of such glue. In the circle of non-perturbative fundamental entities in QCD,we argue that there should exist a new member_the constituent gluon,it should be emerged in high energy h-h′ strong-soft processes,and the gluballs are produced via two constituent gluons fusion. Finally,we conjecture there may be an averaged dual relation between the glueballs and the Pomeron,but this correspondence may become as multi-to-one homologue.
