This award funds the research activities of Professors Csaba Csaki, Yuval Grossman, Thomas Hartman, Liam McAllister, and Maxim Perelstein at Cornell University.Observations of the cosmos, combined with terrestrial experiments in particle physics, have given physicists a glimpse of the fundamental laws that govern our universe. The research supported by this award includes the study of mathematical and conceptual aspects of quantum mechanics and gravity, as well as the investigation of observable phenomena in particle physics, astrophysics, and cosmology. Professors Csaki, Grossman, and Perelstein will research the physical laws governing the known fundamental particles, as well as new hypothesized particles known as monopoles and axions, and will investigate possible explanations for the dark matter in the universe. Professor Hartman will study how quantum mechanics and gravity affect the properties of black holes. Professor McAllister will research possible signatures of quantum gravity in the observable universe. This work will impact the design and interpretation of new experiments. Theoretical work in this area advances the national interest by strengthening the foundations on which other scientific progress can be built. This research will also have significant broader impacts: the investigators will work closely with graduate students and postdocs, thereby contributing to training the next generation of physicists. The investigators will also give public lectures and colloquia to convey the results of their research to a broader audience, in the hope of inspiring a deeper appreciation of science in the community.More technically, Professor Csaki will investigate the physics of magnetic monopoles using his novel method of pairwise helicity, study the phases of gauge theories, and examine cosmological solutions to the hierarchy problem and the cosmological constant problem. Professor Grossman will study flavor physics and investigate the neutrino force. Professor Hartman will study connections between entanglement and geometry in quantum gravity, and also develop new techniques to solve strongly interacting field theories with the conformal bootstrap. Professor McAllister will study four-dimensional solutions of string theory and characterize the physics of axions in string theory. Professor Perelstein will construct novel models of dark matter and study their experimental and observational signatures; develop strategies to search for new physics at the LHC and future colliders; and explore the potential of fixed-target experiments with beam dumps to search for dark photons, axion-like particles, and other 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.

该奖项资助康奈尔大学的Csaba Csaki、Yuval Grossman、Thomas Hartman、Liam McAllister和Maxim Perelstein教授的研究活动。对宇宙的观测，结合地球上的粒子物理实验，使物理学家得以一窥支配我们宇宙的基本定律。该奖项支持的研究包括量子力学和引力的数学和概念方面的研究，以及粒子物理、天体物理和宇宙学中的可观察现象的调查。卡萨基、格罗斯曼和佩雷尔斯坦教授将研究支配已知基本粒子的物理定律，以及被称为单极子和轴子的新假想粒子，并将调查宇宙中暗物质的可能解释。哈特曼教授将研究量子力学和引力如何影响黑洞的性质。麦卡利斯特教授将研究可观测宇宙中量子引力的可能特征。这项工作将对新实验的设计和解释产生影响。这一领域的理论工作加强了其他科学进步的基础，从而促进了国家利益。这项研究还将产生重大的更广泛的影响：研究人员将与研究生和博士后密切合作，从而为培养下一代物理学家做出贡献。研究人员还将举行公开讲座和座谈会，将他们的研究成果传达给更广泛的受众，希望激发社会对科学的更深层次的欣赏。更严格地说，Csaki教授将使用他的两两螺旋性的新方法研究磁单极子的物理，研究规范理论的相，并研究等级问题和宇宙常数问题的宇宙学解决方案。格罗斯曼教授将研究味道物理学，并研究中微子力。哈特曼教授将研究量子引力中纠缠和几何之间的联系，并开发新技术来解决具有共形自举的强相互作用场论。麦卡利斯特教授将研究弦理论的四维解，并描述弦理论中的轴子物理。佩雷尔斯坦教授将构建新的暗物质模型并研究它们的实验和观测特征；开发在大型强子对撞机和未来对撞机上搜索新物理的策略；探索利用光束转储进行固定目标实验以搜索暗光子、类轴子粒子和其他新物理的潜力。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
