It is believed that the strong forces in atomic nuclei arise from even more elementary constituents, which are known as quarks and gluons. Quarks and gluons are well established in elementary particle physics, however, our knowledge of the role they play for the strong nuclear force is largely unknown. This research project will provide a microscopic understanding of the nuclear forces on this level. The method used is computer simulations of multi- quark and -gluon systems. The focus of the research is similar to the current experimental efforts at Thomas Jefferson National Accelerator Facility and will complement it in some aspects. An Infrastructure Award towards a workstation for performing the lattice gauge calculations is being provided by the Office of Multidisciplinary Activities of the Mathematical and Physical Sciences Directorate.

人们认为，原子核中的强力来自于更基本的成分，即夸克和胶子。 夸克和胶子在基本粒子物理学中已经很好地建立起来，然而，我们对它们在强核力中所起的作用的了解在很大程度上是未知的。 这个研究项目将提供一个微观的理解在这个水平上的核力。 所用的方法是多夸克和多胶子系统的计算机模拟. 该研究的重点与托马斯杰斐逊国家加速器设施目前的实验努力相似，并将在某些方面进行补充。 数学和物理科学理事会多学科活动办公室正在为一个进行格点规范计算的工作站提供基础设施奖。
