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.

芝加哥大学的这项提案要求支持一个参与费米实验室Tevatron CDF实验的小组，费米实验室Tevatron目前是世界上最高的能源加速器。这项研究的特殊目标是理解电弱对称破缺，在粒子物理的标准模型中，这是由希格斯机制描述的，与此机制相关的物理，以及希格斯玻色子本身，都很少被理解和测试。然而，人们可以通过精确测量W-玻色子质量、顶夸克质量和Z-玻色子性质等电弱可观测性，通过量子修正，通过间接探测来推断玻色子的性质。这位研究人员计划用Tevatron Run 2b的数据测量顶夸克的性质，包括它的质量和W质量。她还计划致力于未来的项目，这些项目将为这些物理测量提供更高的灵敏度，即升级Silicon Vertex触发器和ATLAS实验的硬件跟踪器项目。在这项工作中，许多年轻的物理学家，包括代表不足的少数族裔和女性，将得到培训。有关硅和触发系统的工作将加强国际科学联系，预计将对电子技术产生更广泛的影响。
