CAREER: Superior Silicon Tracking and Discovery at CMS and D0

这个提议解决了基本粒子为什么有质量以及为什么这些质量都不同的问题。这些问题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和对其性质的测量将有助于揭示这些历史性的问题。如果考虑像最小超对称标准模型(MSSM)这样的模型，就有可能在费米实验室的Tevatron发现轻希格斯。MSSM预测希格斯产生的截面比标准模型的大一到几个数量级。在第二次运行接近尾声时，积分光度低于4fb-1的情况下，有可能发现中等大小的希格斯玻色子。此外，CDF和D0‘S标准模型希格斯搜索的组合结果将关闭对高达125GeV的希格斯质量的搜索窗口，这是一个在大型强子对撞机上很难探索的质量区域。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的过程中发挥了历史性的作用，PI在构建和优化此类设备的性能并使用它们来设置世界上对希格斯玻色子质量的最佳限制方面有着长期的经验。这项工作将继续建造CMS正向像素探测器，并建造一个小型实验室，用于未来硅探测器的研发。这项提案的教育和推广部分寻找成绩优异的双语(西班牙语-英语)高中生，并将他们与主要是拉丁裔小学生配对，这些小学生每周有两个下午接受辅导。这创造了一种对年轻学生和导师都有利的制度。该项目在费米实验室(BEST)附近成功运作，PI提议在内布拉斯加州林肯建立一个类似的项目。

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.
