This award supports several research projects involving both formal and phenomenological aspects of String Theory and related theories of gravity, and supersymmetric field theories. The main focus of one aspect of theproposal is to attain a deeper understanding of holography, particularly in the time-dependent context through consideration of physical questions such as particle production and initial conditions. Another main area of research is to use exact solutions of supersymmetric gauge theories to explore a range of nonperturbative phenomena, from conformal field theories in 4D to the structure of solitons, with potential extensions to supergravity and string theory. In addition, a program seeking experimentalsignatures and strengthen constraints on low-energy gravity, using data from current and future cosmic ray detectors and particle colliders will be continued. New projects on baryon decay and spacetime foam will augment previous work on black hole production. This research project is expected to enhance the quality of undergraduate and graduate physics education at the University of Kentucky and increase awareness of frontier physics research in an Appalachian region with one of the lowest scientific literacy rates inthe country.

该奖项支持几个研究项目，涉及弦理论和相关引力理论的形式和现象学方面，以及超对称场理论。该提案的一个主要方面是通过考虑粒子产生和初始条件等物理问题来加深对全息术的理解，特别是在依赖时间的背景下。另一个主要的研究领域是使用超对称规范理论的精确解来探索一系列非微扰现象，从四维共形场理论到孤立子的结构，并潜在地扩展到超引力和弦理论。此外，一项利用当前和未来的宇宙线探测器和粒子对撞机的数据，寻求实验特征并加强对低能重力的约束的计划将继续下去。有关重子衰变和时空泡沫的新项目将加强之前在黑洞生产方面的工作。这一研究项目预计将提高肯塔基大学本科生和研究生物理教育的质量，并在阿巴拉契亚地区提高对前沿物理研究的认识，该地区是美国科学识字率最低的地区之一。
