Part IThis NSF CAREER award will support Professor David Miller, at the University of Chicago, in seeking to answer questions about the fundamental structure of matter at a new energy frontier. Specifically, Prof. Miller will extend and enhance his research program using the ATLAS detector at the Large Hadron Collider (LHC), to conduct measurements that will seek out the existence of new TeV-scale particles, and characterize the particles and forces of the Standard Model with greater precision. This will be achieved by developing novel analysis algorithms to search for these new massive particles and advanced high-speed electronics that enhance the performance of the ATLAS detector in key domains. For broader impact, the PI will be leading the Lane Tech High School U. Chicago Outreach Program and the Enrico Fermi Summer Interns Program for 7th graders. In addition, he will bring high-energy physics concepts into undergraduate classrooms, by providing college students with concrete examples of how the core physics curriculum is being used by active researchers at the forefront of science today. Part IIThis NSF CAREER award will extend the PI (Professor David Miller)'s research program, which is focused on developing a comprehensive approach to recognize the most complex hadronic final states in search of new TeV-scale particles. This research includes development of novel analysis algorithms and advanced high-speed electronics. His goal is to search for evidence of Supersymmetry in final states characterized by Lorentz-boosted massive particles using distinct signatures in the ATLAS calorimeter system, and to better understand the Standard Model processes involved that form a large background to these new states. The particles sought should generate multi-jet final states, and new algorithms will be introduced to recognize them. In addition, this effort will be integrated into the development of high-speed electronics for new triggering systems, vital to the future running of Large Hadron Collider (LHC). The PI's group will perform detailed measurements of Standard Model processes that will help to better understand the backgrounds these represent to the new signals sought. Timing of this program corresponds to the higher center of mass energy of Run II at the LHC which should increase the yield of processes such as collinear emission of a W-boson, the intermediate carrier of the weak force and a prime target of study in this work. For broader impact, the excitement and results of this physics program will be communicated through K-12 and undergraduate education programs. These programs will include community outreach activities that target underrepresented students in the City of Chicago. The PI will be leading the Lane Tech High School U. Chicago Outreach Program and the Enrico Fermi Summer Interns Program for 7th graders.

第一部分这个NSF职业奖将支持芝加哥大学的大卫米勒教授寻求在新能源前沿回答有关物质基本结构的问题。 具体来说，米勒教授将使用大型强子对撞机（LHC）的ATLAS探测器扩展和加强他的研究计划，进行测量，寻找新的TeV尺度粒子的存在，并以更高的精度表征标准模型的粒子和力。这将通过开发新的分析算法来搜索这些新的大质量粒子和先进的高速电子设备来实现，这些电子设备可以增强ATLAS探测器在关键领域的性能。为了更广泛的影响，PI将领导莱恩科技高中U。芝加哥外展计划和恩里科费米夏季实习生计划的七年级学生。此外，他还将把高能物理概念带入本科课堂，为大学生提供核心物理课程如何被当今科学前沿的活跃研究人员使用的具体例子。第二部分NSF CAREER奖将扩展PI（大卫教授米勒）的研究计划，该计划的重点是开发一种全面的方法来识别最复杂的强子最终状态，以寻找新的TeV级粒子。这项研究包括开发新的分析算法和先进的高速电子设备。他的目标是使用ATLAS量热计系统中的不同特征来寻找以洛伦兹助推的大质量粒子为特征的最终状态中超对称性的证据，并更好地理解形成这些新状态的大背景的相关标准模型过程。 所寻找的粒子应该产生多射流的最终状态，并将引入新的算法来识别它们。 此外，这项工作将被纳入新触发系统的高速电子设备的开发，这对大型强子对撞机（LHC）的未来运行至关重要。 PI的团队将对标准模型过程进行详细的测量，这将有助于更好地理解这些过程所代表的新信号的背景。 该计划的时间对应于运行II在LHC的更高的质心能量，这应该增加诸如W玻色子的共线发射等过程的产量，W玻色子是弱力的中间载体，也是这项工作的主要研究目标。 对于更广泛的影响，这个物理程序的兴奋和结果将通过K-12和本科教育计划进行沟通。这些计划将包括针对芝加哥市代表性不足的学生的社区外展活动。 PI将领导莱恩科技高中U。芝加哥外展计划和恩里科费米夏季实习生计划的七年级学生。
