Exploration in Gauge Theory, String Theory, and Quantum Cosmology

这里提出的工作旨在更深入地了解自然的基本规律和力量。它以弦理论和超对称规范理论为基础。这些理论模型将量子力学、引力和其他自然力结合在一个统一的框架中。尽管在将弦理论和超对称规范理论与强、电磁和弱相互作用的标准模型以及大爆炸宇宙学联系起来方面取得了许多进展，但需要新的见解来加强这种联系，以便弦理论和超对称可以在实验室和天文台进行测试。这个提议是为了促进芝加哥大学非常强大的弦理论小组与欧洲、以色列和印度的一些一流小组之间的认真的国际合作。将要研究的主题是关于如何更好地理解超对称规范理论并将其与标准模型联系起来的最前沿的想法。同样重要的是理解黑洞熵，以及如何从弦理论和膜世界物理学中产生大爆炸宇宙学。在过去几年中，项目负责人和合作者在这些领域取得了进展，通过改进这项资助将提供的国际合作机制，人们可以期待在这些非常重要的领域取得更大的进展。国际合作将通过不同的人才和视角，以新的视角看待弦理论所面临的问题，从而带来新的方法。美国学生和博士后将受益于多样化的研究和文化环境，并将受益于这些互动和环境。这种合作不仅涉及文化上不同的观点，而且还涉及国际合作者在其伙伴机构的公开演讲

The work proposed here is aimed at a deeper understanding of the basic laws and forces of nature. It is based on string theory and Supersymmetric Gauge Theories. These are theoretical models which combine quantum mechanics and gravity with the other forces of nature in a unified framework. Although lots of progress has been made in connecting String Theories and Supersymmetric Gauge theories to the Standard Model of Strong, Electromagnetic and Weak Interactions, as well as to big bang cosmology, new insights will be needed to make this connection stronger so that String Theory and Supersymmetry can be tested in the laboratory and observatory. This proposal is to foster serious international collaborations between the very strong string theory group at the University of Chicago, with some of the premier groups in Europe, Israel, and India. The subjects that will be investigated are at the very forefront of ideas on how to better understand Supersymmetric Gauge Theories and relate them to the Standard Model. Also of great importance is understanding Black Hole Entropy and how big-bang cosmology can emerge from string theory and brane-world physics. The PI's and collaborators have been leaders in the past few years in making progress in these areas, and by improving the mechanism for international collaboration that this grant will provide, one can expect an increase in the progress in these very important areas. The international collaboration will lead to new ways of looking at the problems confronting String Theory by having diverse talents and perspectives taking a fresh look at the issues. American Students and Post-Docs will benefit in being in diverse research and cultural environments and will benefit from being exposed to these interactions and environments. The collaboration will involve not only culturally different points of view, but also involve public lectures of the International collaborators at their partner institutions
