项目摘要

The Standard Model of particle physics has been a remarkably successful theory, agreeing with several decades of experimental observations involving weak, electromagnetic, and strong interactions. The LHC discovery of the Higgs boson in 2012 was further confirmation of this success. However, the Standard Model remains an incomplete theory as it fails to explain dark matter and it does not provide an explanation for the mass of light neutrinos. Interestingly, these insufficiencies appear to be part of an intriguing overlap in the sciences describing the largest and smallest scales of the universe: proposed extensions of the Standard Model also shed light on our understanding of the evolution of our universe and the dark matter relic density measured by astronomers. This work exploits the rich particle physics program at the Large Hadron Collider at CERN in Geneva, Switzerland to search for dark matter and other physics beyond the Standard Model.The expanding LHC data set collected by the CMS experiment offers significant opportunity for new discovery, providing greater sensitivity for new physics signatures which would address questions in both particle physics and cosmology. This research program is aimed at questions motivated by the synergy between these two disciplines, for example, by using events produced through vector boson fusion processes to search for dark matter and supersymmetry. In addition, this effort leverages searches for TeV-scale particles using tau lepton reconstruction and identification, which combined with other technicques, enables targeted searches for interesting new physics such as dark matter, compressed spectra SUSY, heavy neutrinos, leptoquarks, and new heavy neutral gauge bosons such as Z-prime. This research is also enabled by hardware operations and development work on the CMS pixel detector and on development of advanced machine learning data analysis techniques. In addition, the group will undertake multiple education and outreach activities, including the national initiative Quarknet, research experiences for Vanderbilt undergraduates, hosting intern days for local secondary school students, and hosting a "Dark Matter Fest" for students.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

粒子物理学的标准模型一直是一个非常成功的理论，与涉及弱，电磁和强相互作用的几十年实验观察一致。 2012年，HIGGS玻色子的LHC发现进一步证实了这一成功。但是，标准模型仍然是一个不完整的理论，因为它无法解释暗物质，并且没有为光中微子的质量提供解释。有趣的是，这些不足似乎是描述宇宙最大和最小尺度的科学中有趣重叠的一部分：标准模型的提议扩展也阐明了我们对宇宙演化的理解和深度密度测量的深度。由天文学家。这项工作利用了瑞士日内瓦州Cern的大型强子对撞机的丰富粒子物理计划，以寻找深色物质和标准模型以外的其他物理。CMS实验收集的扩展LHC数据集为新发现提供了重要的机会对新物理学特征的敏感性更大，这将解决粒子物理和宇宙学中的问题。该研究计划的目的是通过这两个学科之间的协同作用，例如，通过使用通过向量玻色子融合过程产生的事件来寻找暗物质和超对称性。此外，这种努力利用Tau Lepton的重建和识别来利用TEV规模的颗粒，结合其他技术，可以针对有针对性的搜索有趣的新物理，例如暗物质，压缩光谱SUSY，重中微子，leptotionos，leptoquark和新的重型中性中性中性中性的中性中性中性中性量规玻色子，例如Z-Prime。这项研究还可以通过CMS像素探测器以及高级机器学习数据分析技术的开发来实现这项研究。此外，该小组还将开展多项教育和外展活动，包括国家倡议Quarknet，范德比尔特大学生的研究经验，为当地中学生举办实习日，并为学生举办“暗物质节”。该奖项反映了NSF的法规。使命，并被认为是通过基金会的知识分子优点和更广泛影响的审查标准通过评估值得支持的。
