摘要:

我们回顾了Yangian对称性在高能QCD唯象学中的应用。回顾了高能QCD的一些基本事实,特别是散射振幅的自旋-螺旋度形式、深度非弹性散射结构函数的标度演化方程以及散射的高能渐近行为。作为工作工具,引入了Yangian对称关联函数,并在$g\ell(n)$型Yangian代数框架下进行了构造。我们展示了其在树状散射振幅及其迭代关系、部分子劈裂振幅、结构函数标度演化方程的核以及描述散射高能渐近行为的方程中的应用。

英文摘要:

We review applications of Yangain symmetry to high-energy QCD phenomenology. Some basic facts about high-energy QCD are recalled, in particular the spinor-helicity form of scattering amplitudes, the scale evolution equations of deep-inelastic scattering structure functions and the high-energy asymptotics of scattering. As the working tool the Yangian symmetric correlators are introduced and constructed in the framework of the Yangian algebra of $g\ell(n)$ type. We present the application to the tree scattering amplitudes and their iterative relation, to the parton splitting amplitudes and the kernels of the scale evolution equations of structure functions and to the equations describing the high-energy asymptotics of scattering.
