论文摘要
对Regge-Pole和双重振幅的数学特性的研究对于它们在高能量现象学中的应用以及它们对弦，SuperString，Branes和其他理论发展的概括都很重要。在本文中，我们研究了两个双重振幅类别之间的相似性和差异：一种具有Mandelstam分析性（Dama），另一个具有对数轨迹（Dual-Log）的相似性和差异。通过使用量子（Q-）变形，揭开了双log振幅的新特征，尤其是涉及其渐近行为和共振光谱的特征。在各个运动区域进行了比较两类的双重振幅：在固定转移的动量渐近，固定角度渐近学和共振区域。
Studies of the mathematical properties of Regge-pole and dual amplitudes are important both for their applications in high energy phenomenology and in their generalizations to strings, superstrings, branes, and other theoretical developments. In the present paper, we investigate the similarities and differences between two classes of dual amplitudes: one with Mandelstam analyticity (DAMA) and another one with logarithmic trajectories (Dual-log). By using quantum (q-) deformations, new features of Dual-log amplitude are unveiled, in particular those concerning its asymptotic behavior and the spectrum of resonances. The two classes of dual amplitudes are compared in various kinematic regions: at fixed transferred momenta asymptotic, fixed angle asymptotic, and in the resonance region.
