标题： Yangian symmetry applied to Quantum chromodynamics

摘要： 我们回顾了Yangian对称性在高能QCD唯象学中的应用。回忆了一些关于高能QCD的基本事实，特别是散射振幅的旋量-螺旋度形式、深非弹性散射结构函数的尺度演化方程以及散射的高能渐近行为。作为工作工具，引入并在$g\ell(n)$类型的Yangian代数框架下构造了具有Yangian对称性的相关函数。我们展示了这些对树散射振幅及其迭代关系、部分子分裂振幅和结构函数尺度演化方程的核以及描述散射高能渐近行为的方程的应用。 显示英文摘要

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.
