手征夸克在高能过程和格点量子色动力学中的应用

Application of chiral quarks to high-energy processes and lattice QCD

Wojciech Broniowski, Enrique Ruiz Arriola

摘要:

本文综述了与高能过程有关的软矩阵元的手征夸克模型的结果。我们讨论了与π介子的广义部分子分布有关的量:部分子分布函数、部分子分布振幅和广义形状因子。模型预测的数据或晶格模拟相比,具有良好的协议。从低夸克模型尺度到实验尺度的QCD演化是该方法的关键组成部分。

英文摘要:

Results of the chiral quark models for the soft matrix elements involving pions and photons, relevant for high-energy processes, are reviewed. We discuss quantities related to the generalized parton distributions of the pion: the parton distribution functions, the parton distribution amplitudes, and the generalized form factors. The model predictions are compared to the data or lattice simulations, with good agreement. The QCD evolution from the low quark model scale up to the experimental scales is a crucial ingredient of the approach.
