Research in High Energy Theoretical Physics

这个项目通过使用高性能的计算机模拟来继续量子色动力学(强相互作用理论)的第一原理研究。重点是使用改进的算法来提取自然界基本相互作用标准模型中关键数字迄今最精确的值。将获得的结果对于分析国家加速器实验室的实验测量和测试模型的内部一致性是必不可少的。它们可能导致关于更基本的相互作用的线索。它们还将用于继续研究封闭物质和夸克-胶子等离子体之间的高温相变，以及等离子体中奇怪的夸克含量。这种相变发生在早期宇宙的演化中，被认为是可以在RHIC加速器的重离子碰撞中实现的，该加速器最近在布鲁克海文国家实验室开始运行。这些研究对于扩大我们对我们物理世界的最基本基础和我们的宇宙起源的理解很重要。算法思想可能会在其他计算领域得到应用。

This project continues first principles studies of quantumchromodynamics (the theory of the strong interactions) through the useof high performance computer simulations. Emphasis is to be placed onusing improved algorithms to extract the most precise values to dateof key numbers in the Standard Model of the fundamental interactionsin Nature. Results to be obtained are essential for analyzingexperimental measurements at national accelerator laboratories and totest the internal consistency of the Model. They may lead to cluesabout more fundamental interactions. They will also be used tocontinue studies of the high temperature phase transition betweenconfined matter and the quark-gluon plasma and of the strange quarkcontent of the plasma. Such a phase transition occurred in theevolution of the early Universe and is thought to be achievable in thelaboratory in collisions of heavy ions at the RHIC accelerator, whichrecently began operation at the Brookhaven National Laboratory.These studies are important for extending our understanding of themost fundamental basis of our physical world and of the origins of ourUniverse. Algorithmic ideas are likely to have applications in othercomputational fields.
