Abstract

Dilaton and axion are ubiquitous in extended supergravities and closed superstrings. We propose new models of modular inflation in four-dimensional $N=1$ supergravity coupled to the chiral dilaton-axion-goldstino supermultiplet, which fit some necessary conditions of superstring cosmology. The model parameters are tuned to obey precision measurements of the cosmic microwave background radiation. We employ the modular-invariant superpotentials and asymptotically modular-invariant K\"ahler potentials, and achieve axion stabilization with high-scale supersymmetry breaking.

超引力中的迪拉顿-轴模态膨胀

稀拉顿和轴子在扩展超引力和封闭超弦中无处不在。我们提出了在四维 $N=1$ 超引力中与手性稀拉顿-轴子-金斯提诺超重子耦合的模块膨胀新模型，它符合超弦宇宙学的一些必要条件。模型参数是根据宇宙微波背景辐射的精确测量结果调整的。我们采用模态不变超势能和渐近模态不变 K\"ahler 势能，实现了轴子稳定与高尺度超对称破缺。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
