Particles such as protons, neutrons and others which have the so-calledstrong or nuclear interactions are made up of more fundamental entitiescalled quarks and gluons. The quarks and gluons can be described by atheory called  Quantum Chromodynamics. Large-scale computer simulationsare used to study Quantum Chromodynamics and test our understanding ofnuclear interactions at a fundamental microscopic level.                                                                                Quarks much heavier than the usual building blocks of protons and neutronshave been discovered. The proposed research deals with calculation ofstrongly interacting systems containing heavy quarks and in particularhow such systems are affected by quantum fluctuations of quark - antiquarksin the vacuum. These studies will provide information which will be usefulfor experiments which may, in the future, search for yet undiscoveredheavy-quark analogs of neutrons and protons.

质子、中子和其他具有所谓强相互作用或核相互作用的粒子是由称为夸克和胶子的更基本的实体组成的。夸克和胶子可以用量子色动力学理论来描述。大规模计算机模拟用于研究量子色动力学并测试我们对基本微观水平上的核相互作用的理解。                                                                                已经发现了比质子和中子的常见构件重得多的夸克。拟议的研究涉及包含重夸克的强相互作用系统的计算，特别是这些系统如何受到真空中夸克-反夸克的量子涨落的影响。这些研究将为未来寻找尚未发现的中子和质子的重夸克类似物的实验提供有用的信息。
