摘要:

排他过程e+ e- -> e+ e-rho ^0_L rho^0_L允许研究微扰QCD的各种动力学和因子分解性质。在中等能量下,我们展示了如何出现共线QCD因子分解,包括广义分布振幅(GDA)和跃迁分布振幅(TDA)。在更高的能量下,在Regge极限的QCD,我们表明,它提供了一个有前途的探测BFKL再确认效应进行研究在国际直线对撞机(ILC)。

英文摘要:

The exclusive process e+ e- -> e+ e- rho^0_L rho^0_L allows to study various dynamics and factorization properties of perturbative QCD. At moderate energy, we demonstrate how collinear QCD factorization emerges, involving generalized distribution amplitudes (GDA) and transition distribution amplitudes (TDA). At higher energies, in the Regge limit of QCD, we show that it offers a promising probe of the BFKL resummation effects to be studied at the International Linear Collider (ILC).
