论文摘要
回顾了自由度自由度在高能强体 - 戴隆和Lepton-Hadron散射中的作用，重点是软，衍射，非扰动效应的主要作用。讨论了基于分析性和Regge-Pole理论的明确模型，包括Pomeron轨迹（$ T $通道中的Gluon交换）。我们认为，根据所考虑的运动学，本质上有一个单一的普遍波美龙，表现为相对“软”或“硬”。恢复轨迹是非线性的，复杂的功能，可预测有限数量的共振。提出了明确的模型和拟合，可用于从深度虚拟的康普顿散射和载体介子的电源生产中恢复广义的Parton分布。
The role of spin degrees of freedom in high-energy hadron-hadron and lepton-hadron scattering is reviewed with emphasis on the dominant role of soft, diffractive, non-perturbative effects. Explicit models based on analyticity and Regge-pole theory, including the pomeron trajectory (gluon exchange in the $t$ channel) are discussed. We argue that there is a single, universal pomeron in Nature, manifest as relatively "soft" or "hard", depending on the kinematics considered. Regge trajectories are non-linear, complex functions, predicting a finite number of resonances. Explicit models and fits are presented that may be used in recovering generalized parton distributions from deeply virtual Compton scattering and electoproduction of vector mesons.
