项目摘要
OISE-0403366BarsThis award supports a three-year collaborative research project between Professor Itzhak Bars at the University of Southern California in Los Angeles and Professor Hirosi Ooguri of the California Institute of Technology and Professor Tohru Eguchi at the University of Tokyo in Japan. They will be undertaking research on string field theory and string geometry. String theory is the central focus of most current effort in fundamental theoretical particle physics. The proposed activity focuses on three essential aspects of string theory, i.e. string field theory (SFT), geometrical and topological aspects of string theory, and the AdS/CFT correspondence. Concerning string field theory, it is proposed to use the Moyal Star Formulation of SFt to construct the supersymmetric theory and develop non-perturbative computational techniques that would help to estimate the true vacuum state and connect the string theory to low energy physics and cosmology. The finding of the true vacuum state in string theory is one of the most relevant open questions in this area of research. In addition, the connection of string theory to low energy physics and cosmology is an essential point to test the predictions of string theory. It is also proposed to continue the current research on applications of topogical string theory to understand perturbative and non-perturbative aspects of superstring compactifications on Calabi-Yau manifolds as well as of supersymmetric Yang-Mills theories arising as limits of these compactifications. These ideas have important implications, as the computation of gravitational corrections to the superpotentials, which are realized in the gauge theory in a novel fashion, leading to an interesting Lorentz violating photon-graviton coupling, with possible astrophysical consequences. In addition, there are very important applications in mathematics. The third aspect of the research involves the AdS/CFT correspondence, which has been one of the central issues of string theory in the last years. This activity is very important to advancing knowledge and understanding in string/M theory. This project brings together the efforts of three laboratories that have complementary expertise and research capabilities. Results of the research will impact the areas of string theory, particle physics and cosmology. The expected broader impact of the proposed activities would be in mathematical areas of non-commutative geometry, group theory, and geometry. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. The project includes the participation of a large number of postdocs and graduate students. Results of the research will be disseminated at scientific meetings and in scientific journals.
OISE-0403366 BarsThis award supported a three-year collaborative research project between Professor Itzhak Bars at the University of Southern加州州in洛杉矶and Professor Hirosi Ooguri of the加州Institute of Technology and Professor Tohru Eguchi at the University of Tokyo in Japan. 他们将从事弦场论和弦几何的研究。 弦理论是当前基础理论粒子物理学的中心焦点。 拟议的活动侧重于弦理论的三个基本方面,即弦场论(SFT),弦理论的几何和拓扑方面,以及AdS/CFT对应。 在弦场论方面,我们建议用Moyal星星公式来构造超对称理论,发展非微扰计算技术,这将有助于估计真实的真空态,并将弦理论与低能物理和宇宙学联系起来。 弦理论中真正真空态的发现是这一研究领域中最相关的未决问题之一。 此外,弦理论与低能物理学和宇宙学的联系是检验弦理论预言的一个关键点。 它还建议继续目前的研究应用拓扑弦理论,以了解微扰和非微扰方面的超弦紧化的卡-丘流形,以及超对称杨-米尔斯理论所产生的限制,这些紧化。 这些想法有重要的意义,作为计算引力修正的超势,这是实现在规范理论中的一种新的方式,导致一个有趣的洛伦兹违反光子引力子耦合,可能的天体物理后果。 此外,在数学中还有非常重要的应用。 研究的第三个方面涉及AdS/CFT对应,这是过去几年弦理论的中心问题之一。 这项活动对于推进弦/M理论的知识和理解非常重要。 该项目汇集了三个具有互补专业知识和研究能力的实验室的努力。 研究结果将影响弦理论、粒子物理学和宇宙学领域。 拟议活动的预期更广泛影响将是在非交换几何、群论和几何等数学领域。 通过交流思想和技术,该项目将扩大我们的基础知识,促进国际理解与合作。 该项目包括大量博士后和研究生的参与。研究结果将在科学会议和科学期刊上传播。
