宇宙学与超引力

Cosmology and Supergravity

S. Ferrara, A. Kehagias, A. Sagnotti

摘要:

阿卜杜勒·萨拉姆是20世纪理论物理学的真正大师。他不仅是标准模型的先驱(他与S. Weinberg),但他也(共同)撰写了许多其他杰出的贡献领域的基本相互作用和他们的统一。特别是,他是超对称理论发展的主要贡献者,在那里他还创造了“超对称”这个词(取代了早期从弦论中得出的“超规范”)。他还介绍了“超空间”的基本概念和“戈德斯通费米子”的概念(戈德斯蒂诺)。这些概念被证明有助于探索紫外性质和研究超杨-米尔斯理论和超引力的自发破裂相。他们继续在早期宇宙学的当前发展中发挥关键作用。在这篇文章中,我们回顾了基于自发破缺局部超对称性的超引力的暴胀模型,重点是幂零超场在描述我们宇宙的de Sitter相位中的作用。

英文摘要:

Abdus Salam was a true master of 20th Century Theoretical Physics. Not only was he a pioneer of the Standard Model (for which he shared the Nobel Prize with S. Glashow and S.Weinberg), but he also (co)authored many other outstanding contributions to the field of Fundamental Interactions and their unification. In particular, he was a major contributor to the development of supersymmetric theories, where he also coined the word "Supersymmetry" (replacing the earlier "Supergauges" drawn from String Theory). He also introduced the basic concept of "Superspace" and the notion of "Goldstone Fermion"(Goldstino). These concepts proved instrumental for the exploration of the ultraviolet properties and for the study of spontaneously broken phases of super Yang-Mills theories and Supergravity. They continue to play a key role in current developments in Early-Universe Cosmology. In this contribution we review models of inflation based on Supergravity with spontaneously broken local supersymmetry, with emphasis on the role of nilpotent superfields to describe a de Sitter phase of our Universe.
