AI 中文摘要
本文探讨了振幅的Regge因子化与强子截面的Collins-Soper-Sterman因子化之间的关系。为寻求高能散射中快度发散与横向动量依赖因子化的统一描述，Collins-Soper核与Regge轨迹之间出现了联系。这为桥接高能与低横向动量重求和提供了一个框架，并为未来将$k_T$-因子化推广到超越领头对数精度奠定了基础。
英文摘要
The relationship between Regge factorization of amplitudes and the Collins-Soper-Sterman factorization of hadronic cross sections is explored. Seeking a unified description of rapidity divergences in high-energy scattering and transverse-momentum-dependent factorization, a connection emerges between the Collins-Soper kernel and the Regge trajectory. This provides a framework for bridging high-energy and low-transverse-momentum resummation and for future extensions of $k_T$-factorization beyond leading-logarithmic accuracy.
