Research in Theory of Elementary Particles and Cosmology

斯坦福大学高能理论小组提出了一个广泛的研究计划，研究理论物理的前沿。随着大型强子对撞机开始运行，基本粒子物理学即将进入一个新时代。迪莫普洛斯将继续他的建模工作，以理解来自这台机器的数据。为了达到同样的目的，卡赫鲁和西尔弗斯坦将继续研究超对称破缺的机制，包括特别严格的机制。他们还将探索调解机制和模型构建的其他方面，这些都是弦理论中自然存在的。宇宙学，特别是暴涨是斯坦福小组的中心兴趣。一个重要的主题将是更好地理解弦理论中的亚稳态真空，以及更广泛的弦景观的结构。这将包括建立在KKLT(Kachru，Kallosh，Linde，Trivedi)建设和Silverstein及其合作者工作的想法。林德、申克和苏斯金德将继续研究令人费解的永恒通胀现象。这些研究将包括测量问题和全息定义方面的工作。卡赫鲁、卡洛什和林德将继续努力建立缓慢卷曲膨胀的严格模型，并研究引力子质量和引力波产生的现象学限制。林德和苏斯金德将研究相对较少的缓慢卷曲膨胀的电子折叠的现象学后果。申克和西尔弗斯坦将继续在弦理论的背景下研究类太空奇点的解析，如大爆炸和黑洞奇点。迪莫普洛斯将继续探索如何使用原子干涉仪技术来构建新的重力波探测器，并实施对广义相对论的尖锐测试。弦论的基本结构长期以来一直是这个小组关注的焦点。这方面的活动包括Silverstein？S进一步研究D-对偶和卡洛什？S提出的关于吸引子和黑洞组合的工作。作为各自领域的领导者，斯坦福小组的成员将继续指导研究生和博士后。他们还将继续努力向更广泛的公众传播物理学。与过去一样，这些努力将包括设计和开发针对非物理学家的课程、举办公开讲座、撰写受欢迎的文章和书籍，以及参与制作针对普通公众的电影和视频。

The Stanford High Energy Theory Group proposes a broad program of researchat the leading edge of theoretical physics. Elementary particle physics is poised to enter a new era as the Large Hadron Collider begins operation. Dimopoulos will continue his model building efforts to understand the data coming from this machine. Toward the same end Kachru and Silverstein will continue to investigate mechanisms of supersymmetry breaking, including distinctively stringy ones. They will also explore mediation mechanisms and other aspects of model building that are natural in string theory. Cosmology and especially inflation is a central interest of the Stanford group.An important topic will be to better understand metastable vacua in string theory and more generally the structure of the string landscape. This will include ideas building on the KKLT (Kachru, Kallosh, Linde, Trivedi) construction and work of Silverstein and collaborators. Linde, Shenker and Susskind will continue to study the puzzling phenomenon of eternal inflation. These studies will include work on the measure problem and on holographic definitions. Kachru, Kallosh and Linde will continue their efforts to build stringy models of slow roll inflation and to study the phenomenologicalconstraints on the gravitino mass and gravity wave production. Linde and Susskind will study the phenomenological consequences of a relatively small number of e-foldings of slow roll inflation. Shenker and Silverstein will continue to study resolutions of spacelike singularities like the big bang and the black hole singularity in the context of string theory. Dimopoulos will continue to explore how atom interferometer techniques can be used to construct novel gravity wave detectors and implement sharp tests of General Relativity. The basic structure of string theory has long been a focus of this group.Examples of activities in this direction include Silverstein?s further study of D-duality and Kallosh?s proposed work on attractors and black hole composites.As leaders in their fields, members of the Stanford group will continue to mentor graduate students and postdocs. They will also continue their efforts to communicate physics to the broader public. As in the past these efforts will include the design and development of courses aimed at non-physicists, giving public lectures, writing popular articles and books, and participating in the making of films and videos aimed at the general public.
