This is a group proposal in computational high energy physics to be carried out by theMILC Collaboration. This research addresses fundamentalquestions in high energy and nuclear physics, and is directly related to majorexperimental programs in these fields. It requires very large scale numerical calculationsthat are widely recognized as one of the grand challenges of computational science.The human resources proposed here will enable us to attack several crucial new physicsissues. These include (1) a study of the electromagnetic effects and nonperturbative massrenormalization needed to obtain a precise determination of the masses of the light quarks(2) a new high-precision theoretical determination of the nucleon mass (3) a determinationof mixing parameters for the B and K mesons needed to fix fundamental constants in natureand (4) a study of the thermodynamics of the quark-gluon plasma at nonzero nucleardensity. These initiatives require the development of new application codes within theMILC framework, the running of those codes, and the detailed analysis of the output toextract the relevant physical results. This project supports the needed postdoctoralresearch associates to carry this work to fruition.

这是由MILC合作完成的计算高能物理中的一个小组建议。这项研究涉及高能物理和核物理中的基本问题，并与这些领域的主要实验计划直接相关。它需要非常大规模的数值计算，这被广泛认为是计算科学的重大挑战之一。这里提出的人力资源将使我们能够攻击几个关键的新物理问题。其中包括(1)精确测定轻夸克质量所需的电磁效应和非微扰质量正规化的研究(2)新的高精度核子质量理论测定(3)确定自然中基本常数所需的B介子和K介子的混合参数以及(4)非零核密度下夸克胶子等离子体的热力学研究。这些举措要求在多边ILC框架内开发新的应用程序代码，运行这些代码，并对输出进行详细分析，以提取相关的物理结果。该项目支持所需的博士后研究人员，以实现这项工作。
