This proposal from the University of Chicago requests support for a group participating in the CDF experiment at the Fermilab Tevatron, currently the world's highest energy accelerator. The particular goal of this research is to understand electroweak symmetry breaking, which in the Standard Model of particle physics is described by the Higgs mechanism, The physics associated with this mechanism, and the Higgs boson itself, is poorly understood and tested. However, one can infer the properties of the boson by indirect probes using precision measurements of electroweak observables such as the W-boson mass, the top-quark mass and the Z-boson properties via quantum corrections. This investigator plans to measure the top-quark properties, including its mass, and the W mass with the Tevatron Run 2b data. She also plans on working on future projects that will provide better sensitivities to these physics measurements, namely the upgrade of the Silicon Vertex Trigger and the hardware track finder project for the ATLAS experiment.During this work, many younger physicists, including under-represented minorities and women, will be trained. The work on the silicon and triggering systems will strengthen international ties in science and can be expected to have a broader impact on the electronics technology.

芝加哥大学的这一提议要求支持一个参加CDF实验的小组Fermilab Tevatron，这是目前是世界上最高能源加速器的Fermilab Tevatron。这项研究的特殊目的是了解电动对称性破裂，在粒子物理的标准模型中，Higgs机制描述了与该机制相关的物理学以及Higgs Boson本身的物理学，并且对其进行了鲜明的理解和测试。但是，人们可以使用Electroweak可观测值的精确测量（例如W-boson质量，顶级夸克质量和Z-Boson特性）通过量子校正来推断玻色子的性质。该研究者计划衡量Quark属性，包括其质量和带有Tevatron运行2B数据的W质量。她还计划研究未来的项目，这些项目将对这些物理测量，即硅顶点触发器的升级以及Atlas实验的硬件轨道查找器项目的升级。在这项工作中，许多年轻的物理学家，包括代表性不足的少数民族和女性在内的许多年轻物理学家都将接受培训。在硅和触发系统上的工作将加强科学领域的国际联系，并有望对电子技术产生更广泛的影响。
