This award funds the research activities of Professors Kevork Abazajian, Mu-Chun Chen, Jonathan Feng, Manoj Kaplinghat, Arvind Rajaraman, Michael Ratz, Yuri Shirman, and Timothy Tait at the University of California, Irvine.Particle physics stands at a crossroads. The discovery of the Higgs boson at the Large Hadron Collider has completed the Standard Model of particle physics, but many mysteries remain. Observations of the Universe indicate components such as dark energy and dark matter which the Standard Model does not describe, and the fact that the Universe is predominantly composed of matter (as opposed to anti-matter) and the need to incorporate gravity both point to dynamics beyond those contained within it. Understanding these mysteries requires theoretical interpretation to realize the implications of the vast amount of data currently being collected by particle physics experiments such as the Large Hadron Collider, and cosmological observations, and to propose future experimental searches. The research supported by this award will develop innovative ideas in particle physics, cosmology, and at their interface, to address outstanding problems in a wide variety of fields, including searches for new particles, neutrino physics, the nature of dark matter and its observable signatures, and particle cosmology. It advances the national interest by promoting the progress of science in its most fundamental directions: the work will deepen our understanding of the physical Universe at both the smallest and largest length scales and further our knowledge of the basic building blocks and forces that make up and shape our Universe. The broader impacts of the group's activities are aimed at increasing public interest in and improving public understanding of the exciting results of physics and astronomy research. The group's activities include developing and teaching a COSMOS summer course on particle physics and cosmology to high-achieving high school students from diverse socio-economic backgrounds, programs to strengthen the representation of underrepresented minorities in physics and other STEM fields, a wide array of public talks and outreach activities through print and web-based media, the training of postdoctoral researchers and graduate students both at UC Irvine and around the world, and significant contributions in the area of professional service.More technically, the research will be accomplished by applying cutting edge tools in theoretical physics, including quantum field theory, numerical simulations, and machine learning algorithms to advance our understanding of particle physics and cosmology to propose new models of fundamental particles and interactions, to realize the implications of the vast amount of data currently being collected by particle physics experiments and cosmological observations, and to propose future experimental searches. Through applications of these techniques, this work will advance our knowledge of dark matter, neutrino physics, and particle cosmology.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.

该奖项资助了加州大学欧文分校的Kevork Abazajian、Mu-Chun Chen、Jonathan Feng、Manoj Kaplinghat、Arvind Rajaraman、Michael Ratz、Yuri Shirman和Timothy Tait教授的研究活动。粒子物理学正处于十字路口。 在大型强子对撞机上发现的希格斯玻色子完成了粒子物理学的标准模型，但许多谜团仍然存在。 对宇宙的观测表明了标准模型没有描述的暗能量和暗物质等成分，以及宇宙主要由物质组成的事实（与反物质相对）和需要纳入引力都指向动力学超越那些包含在它。理解这些奥秘需要理论解释，以实现目前正在大量的数据的含义。收集的粒子物理实验，如大型强子对撞机，宇宙观测，并提出未来的实验搜索。 该奖项支持的研究将在粒子物理学，宇宙学及其界面上开发创新思想，以解决各种领域的突出问题，包括寻找新粒子，中微子物理学，暗物质的性质及其可观察到的特征，以及粒子宇宙学。 它通过促进科学在最基本方向上的进步来促进国家利益：这项工作将加深我们对最小和最大长度尺度的物理宇宙的理解，并进一步了解构成和塑造我们宇宙的基本组成部分和力量。该小组活动的更广泛影响旨在提高公众对物理学和天文学研究令人兴奋的成果的兴趣和了解。该小组的活动包括开发和教授粒子物理学和宇宙学的COSMOS夏季课程，以提高来自不同社会经济背景的高中生的成绩，加强在物理学和其他STEM领域代表性不足的少数民族的代表性的计划，通过印刷和网络媒体，在加州大学欧文分校和世界各地培养博士后研究人员和研究生，并在专业服务领域做出重大贡献。从技术上讲，研究将通过应用理论物理学的尖端工具来完成，包括量子场论，数值模拟和机器学习算法，以促进我们对粒子物理学和宇宙学的理解，提出基本粒子和相互作用的新模型，实现目前通过粒子物理实验和宇宙学观测收集的大量数据的含义，并提出未来的实验搜索。 通过这些技术的应用，这项工作将推进我们对暗物质，中微子物理学和粒子宇宙学的知识。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
