For the past two decades, string theory has been one of the most intensely investigated areas of theoretical high-energy physics. This is true chiefly because string theory offers what is currently the most successful method of unifying gravity with the other fundamental forces (strong, weak, and electromagnetic). In this project, Professor Ovrut and his collaborators seek to create an international and interdisciplinary research group that will formulate a wide class of realistic string models, and, within this context, calculate fundamental properties of particle physics and cosmology. Among the physics goals is to predict the mass spectrum of the new supersymmetric particles, explore possible new physics just above the electroweak scale, numerically compute Yukawa couplings, explore the implications of these theories for cosmology, and confront these theories with the data from the LHC and cosmological observations.This project is also envisioned to have considerable broader impacts. Primary among these is the synergy of bringing together representatives of three disciplines (string theory, mathematics, and cosmology) in three different countries to solve some of the most fundamental problems in modern science. This work could therefore become a vehicle for enhancing American and European scientific cooperation, as well as a concrete mechanism to train post-doctoral associates and graduate students in a multinational educational environment. In particular, this work will give American and European students and post-doctoral associates unparalleled opportunities to study, conduct research and attend specialized courses, workshops, conferences and schools organized at our participating universities, Centers, Institute and Laboratory. There is also significant outreach potential by communicating the content of the research to interested non-scientists through public lectures and the media.

在过去的二十年里，弦理论一直是理论高能物理研究最深入的领域之一。 这是正确的，主要是因为弦理论提供了目前最成功的统一引力与其他基本力（强力、弱力和电磁力）的方法。 在这个项目中，Ovrut教授和他的合作者寻求创建一个国际和跨学科的研究小组，将制定广泛的现实弦模型，并在此背景下，计算粒子物理学和宇宙学的基本属性。 物理学的目标包括预测新超对称粒子的质谱，探索电弱尺度之上可能的新物理，数值计算汤川耦合，探索这些理论对宇宙学的影响，并将这些理论与LHC和宇宙学观测的数据进行对比。该项目也被认为具有相当广泛的影响。 其中最重要的是将三个不同国家的三个学科（弦理论、数学和宇宙学）的代表聚集在一起，以解决现代科学中一些最基本的问题。 因此，这项工作可以成为加强美国和欧洲科学合作的工具，以及在多国教育环境中培养博士后和研究生的具体机制。 特别是，这项工作将为美国和欧洲的学生和博士后提供无与伦比的学习，研究和参加在我们参与的大学，中心，研究所和实验室组织的专业课程，研讨会，会议和学校的机会。通过公开讲座和媒体向感兴趣的非科学家传播研究内容，也有很大的推广潜力。
