This award funds the research activities of Professors Ikaros Bigi, Antonio Delgado, and Adam Martin at the University of Notre Dame. While often called an atom-smasher, the Large Hadron Collider (LHC) can also be described as the world's biggest microscope. By studying collisions of particles at the highest energies, particle physicists can gain insight into the building blocks of the universe at the scale of a billionth of a billionth of a meter. In coming years, the LHC will explore even smaller scales and with improved accuracy. Combining these results with results from complimentary terrestrial and astrophysical experiments, particle physicists will hunt for new particles and forces. As part of this global effort, the research of Professors Bigi, Delgado, and Martin aims to illuminate the fundamental rules governing the universe, and thereby advances the national interest by promoting the progress of fundamental science in the United States. In particular, Professors Bigi, Delgado, and Martin focus on investigating what new phenomena may exist, how we might measure it at the LHC or in other experiments, and how it can be connected to pressing questions such as the identity of dark matter or why there is more matter than antimatter. Specific directions to be explored include effective field theory, new LHC searches, and flavor physics. This work is also envisioned to have broad impact in that it will guide future experimental searches and involve close collaboration with experimenters, both locally and at the CERN laboratory where the LHC is located. Professors Bigi, Delgado, and Martin will also continue their activities lecturing at graduate-physics summer schools, organizing workshops and conferences around the world, and teaching particle physics to high-school teachers and students through QuarkNet, both nationally and internationally.More technically, Professor Martin will use Hilbert-series techniques to improve effective field theory-based searches for new phenomena. Professor Delgado will explore novel resonances signals at the LHC, both in the context of simplified models and from a "clockwork" dimension. Together, Professors Martin and Delgado will explore models of Dirac supersymmetry and investigate novel ways to hunt for dark matter, such as through interference in visible final states at the LHC or in high nuclear-recoil bins of direct-detection experiments. Professor Bigi will continue his work investigating the effects of new physics in flavor-violating processes. Such processes are rare in the Standard Model and can therefore provide a smoking-gun signal of new physics.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.

该奖项资助了圣母大学教授Ikaros Bigi，Antonio Delgado和Adam Martin的研究活动。大型强子对撞机（LHC）通常被称为原子加速器，但它也可以被描述为世界上最大的显微镜。通过研究最高能量下的粒子碰撞，粒子物理学家可以在十亿分之一米的尺度上洞察宇宙的组成部分。 在未来几年，LHC将探索更小的尺度，并提高精度。将这些结果与地球和天体物理实验的结果相结合，粒子物理学家将寻找新的粒子和力。作为这一全球努力的一部分，Bigi、Delgado和Martin教授的研究旨在阐明宇宙的基本规则，从而通过促进美国基础科学的进步来促进国家利益。特别是，Bigi，Delgado和Martin教授专注于研究可能存在的新现象，我们如何在LHC或其他实验中测量它，以及它如何与紧迫的问题联系起来，例如暗物质的身份或为什么物质比反物质多。有待探索的具体方向包括有效场论，新的LHC搜索和风味物理。这项工作也被认为具有广泛的影响，因为它将指导未来的实验搜索，并涉及与实验人员的密切合作，无论是在当地还是在大型强子对撞机所在的欧洲核子研究中心实验室。 Bigi教授、Delgado教授和Martin教授也将继续他们的活动，在研究生物理暑期学校讲课，在世界各地组织研讨会和会议，并通过QuarkNet向高中教师和学生教授粒子物理学，无论是在国内还是国际上。从技术上讲，Martin教授将使用希尔伯特系列技术来提高有效的基于场论的新现象搜索。 德尔加多教授将在大型强子对撞机上探索新的共振信号，无论是在简化模型的背景下，还是从“发条”维度。马丁教授和德尔加多教授将共同探索狄拉克超对称性模型，并研究寻找暗物质的新方法，例如通过在大型强子对撞机或直接探测实验的高核反冲仓中干涉可见的最终状态。 Bigi教授将继续他的工作，研究新物理学在违反风味过程中的影响。 这种过程在标准模型中是罕见的，因此可以提供新物理学的确凿信号。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
