AI 中文摘要
我们研究了程函和U矩阵幺正化方案的关键特征，并应用这两个框架来研究弹性散射振幅的高能行为，考虑其渐近行为仅由坡密子交换驱动的输入振幅。特别关注评估提取的坡密子参数如何依赖于假定的轨迹形式。在此背景下，我们比较线性和非线性坡密子轨迹，评估它们对数据现象学描述和拟合参数稳定性的影响。
英文摘要
We examine key features of the eikonal and $U$-matrix unitarization schemes and apply both frameworks to investigate the high-energy behavior of the elastic scattering amplitude, considering input amplitudes whose asymptotic behavior is driven exclusively by Pomeron exchange. Particular attention is devoted to assessing how the extracted Pomeron parameters depend on the assumed trajectory form. In this context, we compare linear and nonlinear Pomeron trajectories, evaluating their impact on the phenomenological description of the data and on the stability of the fitted parameters.
