格子上强子结构计算的评述

Review of Hadron Structure Calculations on a Lattice

Sergey Syritsyn

摘要:

本文综述了强子结构的格点量子色动力学计算的现状和最新成果。首先,我概述了核子结构“基准”量的状态和系统的不确定性,这些量是众所周知的实验,并作为格点量子色动力学方法的有效性的参考点。接下来,我将讨论核子形状因子计算的现状,并着重介绍对理解其内部动力学非常重要的其他强子的一些最新结果。强子的波函数和它们的激发也可以在格点量子色动力学中进行研究,我用最近的两个计算例子来说明。最后,我详细讨论了核子自旋之谜的计算状态。

英文摘要:

I present a review of the current status and the most recent achievements in lattice QCD calculations of hadron structure. First, I overview the status and systematic uncertainties of nucleon structure "benchmark" quantities that are well known from experiments and serve as a reference point for the validity of lattice QCD methods. Next, I discuss the current status of calculations of form factors of the nucleon and highlight some recent results for other hadrons that are important for understanding their internal dynamics. Wave functions of hadrons and their excitations may also be studied in lattice QCD, and I illustrate it with two recent examples of such calculations. Finally, I discuss in detail the state of calculations pertaining to the nucleon spin puzzle.
