In the present contribution, efforts are made to develop an insight between two verticals of strong interaction phenomenology, namely the archaic Regge theory and an avant-garde Hadron dynamics. Even before the advent of quantum chromodynamics (QCD), Regge theory served as an effective tool in the understanding of the high energy limit of hadronic scattering processes and thereby Hadron dynamics. Regge theory provided a study mathematical framework based upon the theory of the complex angular momentum. It related the high energy behaviour of hadronic scattering processes to the singularities of the scattering amplitude in the complex angular momentum plane. With the advent of QCD, Regge formalism was however shunted to the background. Perhaps, the development of large accelerator centres such as CERN and BNL have led to the detection of large number of hadronic resonances and thus have rekindled interest in the Regge Theory specifically with the aid of Regge trajectories which are traced from these resonances. Theoretical and experimental modelling of Regge theory are now proving to be a successful venture.

Regge理论与强子动力学之间关系的见解

在当前的贡献中,人们努力在强相互作用现象学的两个垂直方向之间发展见解,即古老的Regge理论和前卫的Hadron动力学。甚至在量子色动力学(QCD)出现之前,雷格理论就成为了了解强子散射过程的高能量极限以及强子动力学的有效工具。Regge理论提供了基于复角动量理论的研究数学框架。它把强子散射过程的高能行为与复角动量平面中散射幅度的奇异性联系起来。随着QCD的到来,Regge形式主义被转移到了后台。也许,大型加速器中心(如CERN和BNL)的发展导致检测到大量强子共振,因此特别是借助从这些共振中追踪到的Regge轨迹,重新引起了人们对Regge理论的兴趣。Regge理论的理论和实验模型现已证明是一项成功的尝试。
