This proposal addresses why the fundamental particles have masses and why these masses are all different. Thesae are some of the most important outstanding questions in particle physics. The discovery of Higgs bosons and measurements of their properties would shed light on these historic questions. It may be possible to discover a light Higgs at the Fermilab Tevatron if models such as the minimal supersymmetric standard model (MSSM) are considered. MSSM predicts Higgs production cross sections one to several orders of magnitude larger than those of the standard model. Near the end of Run II, with integrated luminosities of less than 4 fb-1, it could be possible to discover Higgs bosons at moderately large values. In addition, the combined results of CDF and D0's standard model Higgs search would close the search window on Higgs masses up to 125 GeV, a mass region that will be difficult to explore at the LHC. These physics and tracking studies will bridge the gap between the Tevatron and the LHC. Precision silicon detectors have played an historic role in the search for the Higgs boson and the PI has a long experience with building and optimizing the performance of such devices and using them to set the world's best limits on the mass of the Higgs. This work will continue with the construction of the CMS forward pixel detector and the construction of a small lab for future R&D into silicon detectors. The education and outreach part of this proposal seeks out high achieving bi-lingual (Spanish-English) high school students and pairs them with mostly Latino elementary school students who are tutored two afternoons per week. This creates a system that is beneficial for both the younger students and the tutors. The program has worked successfully near Fermilab (BEST) and the PI proposes to start a similar one based in Lincoln, Nebraska.

这个提议解决了为什么基本粒子有质量，为什么这些质量都是不同的。这些是粒子物理学中一些最重要的悬而未决的问题。希格斯玻色子的发现及其性质的测量将为这些历史性问题提供线索。如果考虑最小超对称标准模型（MSSM）等模型，那么在费米实验室的Tevatron中发现轻希格斯粒子是可能的。MSSM预测希格斯粒子的产生截面比标准模型的大一到几个数量级。在第二轮接近尾声时，积分光度小于4 fb-1，有可能发现中等大值的希格斯玻色子。此外，CDF和D 0的标准模型希格斯粒子搜索的综合结果将关闭希格斯粒子质量高达125 GeV的搜索窗口，这是一个在LHC难以探索的质量区域。这些物理和跟踪研究将弥合Tevatron和LHC之间的差距。精密硅探测器在寻找希格斯玻色子方面发挥了历史性的作用，PI在构建和优化此类设备的性能以及使用它们来设定希格斯质量的世界最佳限制方面拥有长期经验。这项工作将继续与建设的CMS前向像素探测器和建设一个小型实验室，为未来的研发到硅探测器。该提案的教育和推广部分旨在寻找成绩优异的双语（西班牙语-英语）高中生，并将他们与每周两个下午接受辅导的大多数拉丁裔小学生配对。这创造了一个对年轻学生和导师都有利的系统。该计划在费米实验室（BEST）附近取得了成功，PI建议在内布拉斯加州的林肯开始一个类似的计划。
