QCD higher-order radiative corrections and precision determinations of quark masses

夸克是存在于原子核中的基本粒子。在这个研究项目中，我们进行了精确的理论计算，以解释由夸克及其反粒子组成的物理系统的性质。特别是，我们完成了夸克间力的计算，这已经要求了十多年。这一结果有很大的应用价值，并已用于夸克质量和其它物理参数的初步测定。此外，我们建立了一个理论框架，这是必要的，在当前的LHC实验准确地确定顶夸克质量。

Quarks are elementary particles which reside in atomic nuclei. In this research project, we performed precise theoretical computations for explaining the nature of the physical systems composed by a quark and its anti-particle. In particular, we completed computation of the interquark force which has been demanded for more than a decade. The result has a lot of applications and has already been applied to preliminary determinations of quark masses and other physical parameters. Furthermore, we constructed a theoretical framework which is necessary for determining the top quark mass accurately at the current LHC experiment.
