标题： High-energy factorization via eigenfunctions of the next-to-leading-order BFKL kernel

摘要： 我们通过Chirilli和Kovchegov构造的Balitsky-Fadin-Kuraev-Lipatov（BFKL）核的 {\em 次领头阶} 特征函数，给出了扰动量子色动力学（QCD）半硬区域内前向-exclusive 有Hadron过程振幅的一个普遍公式。 我们讨论了与基于使用 {\em 领导阶次} BFKL特征函数的类似公式兼容性检查的一些形式上的细微之处。 最后，在两个轻矢量介子电产生这一特定情况下，我们考虑了采用其中一个特征函数集时振幅的数值稳定性。 显示英文摘要

摘要： We present a general formula for the amplitude of forward exclusive hadronic processes in the semihard regime of perturbative Quantum Chromodynamics (QCD), by means of the {\em next-to-leading order} eigenfunctions of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) kernel, as constructed by Chirilli and Kovchegov. We discuss some formal subtleties in the check of compatibility with the similar formula based on the use of the {\em leading-order} BFKL eigenfunctions. Finally, in the specific case of the electroproduction of two light vector mesons, we consider the numerical stability of the amplitude when one or the other set of eigenfunctions is adopted.
