This award funds the research activities of Professors Will Kinney, Dejan Stojkovic, Doreen Wackeroth, and Ciaran Williams at the University at Buffalo, The State University of New York. The PIs will conduct a wide-ranging research program which aims to provide answers to key open questions at the frontier of particle physics, cosmology, and gravity research. Research topics to be investigated span a large range, including the physics of cosmological inflation, the physics of black holes, the physics of Dark Energy (which is believed responsible for driving accelerated cosmological expansion), the properties of the Higgs boson, and studies of the theory that underlies the strong interaction and its effects at the Large Hadron Collider (LHC) and at future accelerators. This research aligns with NSF's mission to promote the progress of science and advance the national welfare by performing research aimed at extending our understanding of the origin and structure of the universe, and the properties of fundamental particles and fields. As part of this research, Professors Kinney, Stojkovic, Wackeroth, and Williams will involve graduate students and postdocs in their research and thereby provide training for junior physicists beginning research in this field. The PIs will also continue to conduct public outreach, including public lectures, planetarium shows, interactions with the press and other media, and the Science & Art Cabaret series, now in its twelfth season. More technically, Kinney's research will involve investigation of so-called "swampland" criteria in the context of early-universe physics. He will also seek to constrain the physics of inflation with new observations of the Cosmic Microwave Background and Large-scale Structure, and (in collaboration with Stojkovic) explore possible resolutions of the Hubble tension. Stojkovic will continue the development of a comprehensive event generator BlackMax which is currently used by the LHC collaborations in searches for exotic physics. In collaboration with Wackeroth and Williams, Stojkovic will also explore the gamma-ray and neutrino signatures of bubble production associated with false Higgs-vacuum decay and other cosmological phase transitions. Stojkovic will also study the imposition of observational strong-lensing constraints on a wide class of modified-gravity models. Wackeroth will focus on mixed QCD-Electroweak (EW) corrections to W and Z boson production, which is relevant for a high-precision W-mass measurement. Wackeroth will also provide improved predictions for SM processes which will allow for new tests of non-standard interactions of the top quark and the quartic electroweak self-interactions. Williams will calculate NNLO corrections to Higgs production in association with a b-jet, and will also calculate the mixed QCD-EW terms for the H-to-bb process and use the results to constrain the ultimate precision for the bottom-quark Yukawa coupling which may be reached at future lepton colliders.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.

该奖项为教授Will Kinney，Dejan Stojkovic，Doreen Wackeroth和Ciaran Williams的研究活动提供了资金，该大学的纽约州立大学的研究活动。 PI将进行广泛的研究计划，旨在为粒子物理，宇宙学和重力研究边界的关键开放问题提供答案。 要进行研究的研究主题范围很大，包括宇宙学通胀的物理学，黑洞的物理学，深色能量的物理学（据信负责推动加速的宇宙学扩张），Higgs玻色子的特性以及对大型Hadron Collider（LHCRIDER（LHC）的强大互动及其效应的理论和未来ACCELERATOR的效果。 这项研究符合NSF旨在通过进行旨在扩展我们对宇宙起源和结构的理解以及基本颗粒和领域的特性的研究来促进科学进步并促进民族福利的使命。 作为这项研究的一部分，Kinney，Stojkovic，Wackeroth和Williams教授将涉及研究生和博士后研究，从而为初级物理学家提供培训，以开始在该领域的研究。 PIS还将继续进行公开宣传，包括公开演讲，天文馆表演，与新闻界和其他媒体的互动以及现已进入第十二季的Science＆Art Cabaret系列。 从技术上讲，Kinney的研究将涉及对早期物理学背景下所谓的“ Swampland”标准的调查。 他还将通过对宇宙微波背景和大规模结构的新观察来限制通货膨胀的物理，并（与Stojkovic合作）探讨了哈勃张力的可能分辨率。 Stojkovic将继续开发全面的事件生成器Blackmax，该公司目前由LHC合作进行了搜索外来物理学的搜索。与Wackeroth和Williams合作，Stojkovic还将探索与假Higgs-Vacuum衰减和其他宇宙学相变相关的气泡产生的伽马射线和中微子签名。 Stojkovic还将研究对广泛的修改性重力模型的观察性强透镜约束。 Wackeroth将重点介绍与W和Z玻色子生产的混合QCD-ElectRoweak（EW）校正，这与高精度W-MASS测量相关。 Wackeroth还将为SM过程提供改进的预测，这将允许对顶级夸克和四分之一的Electroweak自相互作用的非标准相互作用进行新的测试。 威廉姆斯（Williams）将计算与B-JET相关的HIGGS生产的NNLO校正，还将计算H-to-BB过程的QCD-EW术语混合术语，并使用结果来限制底价Yukawa耦合的最终精度优点和更广泛的影响审查标准。
