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唯象方面，以及超对称场论。该提案的一个方面的主要重点是通过考虑粒子产生和初始条件等物理问题，加深对全息术的理解，特别是在与时间相关的背景下。 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4D的共形场论到孤子的结构，以及超引力和弦理论的潜在扩展。此外，还将继续开展一项方案，利用当前和未来宇宙射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引力的约束。关于重子衰变和时空泡沫的新项目将加强以前关于黑洞产生的工作。该研究项目有望提高肯塔基州大学的本科生和研究生物理教育质量，并提高阿巴拉契亚地区对前沿物理研究的认识，该地区是全国科学素养最低的地区之一。
