论文摘要
这项工作是我们一系列论文中的延续，该论文介绍了QCD真空结构和晶格结果的动机，探讨了光线上的夸克结构模型。在本文中，我们着重于diquark相关性的重要性，我们通过Instantons引起的准局部四个fermion有效'T HOBETACTION进行了描述。还显示出相同的相互作用会产生额外的夸克 - 易夸克对“海”。它的高阶迭代可以通过“ pion reseded”来包括：两者都会对观察到的古quark海的风味不对称产生定量描述。最后，我们讨论了通过向前DGLAP演变向$ \ sim 1 \，{\ rm Gev}^2 $的手性上刻度的前向DGLAP进化，讨论了弥合Hadronic光谱和Parton可观察物之间差距所需的最后一步。
This work is a continuation in our series of papers, that addresses quark models of hadronic structure on the light front, motivated by the QCD vacuum structure and lattice results. In this paper we focus on the importance of diquark correlations, which we describe by a quasi-local four-fermion effective 't Hooft interaction induced by instantons. The same interaction is also shown to generate extra quark-antiquark pair of the "sea". Its higher order iteration can be included via "pion-mediation": both taken together yield a quantitative description of the observed flavor asymmetry of antiquarks sea. Finally we discuss the final step needed to bridge the gap between hadronic spectroscopy and parton observables, by forward DGLAP evolution towards the chiral upper scale of $\sim 1\, {\rm GeV}^2$.
