较高水平的模块化充盈$N$

Modular Inflation at Higher Level $N$

Monika Lynker, Rolf Schimmrigk

摘要:

我们引入了具有层次结构的模块化通货膨胀的框架,将先前考虑的层次理论推广到更高的层次。我们分析了在这个框架中的CMB观测量的模块化结构,并表明,目标空间的非平凡几何足以确保几乎全纯模块化的相关参数。我们进一步介绍了一个具体的一类模型的基础上hauptmodul功能,提供发电机的相应的通货膨胀潜力在$N>1$。这类模型的现象学为不久的将来的地基CMB实验提供了目标。在我们的模型框架中,我们还讨论了在沼泽地的背景下制定的量子引力理论的地位。

英文摘要:

We introduce the framework of modular inflation with level structure, generalizing the level one theory considered previously to higher levels. We analyze the modular structure of CMB observables in this framework and show that the nontrivial geometry of the target space suffices to ensure the almost holomorphic modularity of the relevant parameters. We further introduce a concrete class of models based on hauptmodul functions that provide generators of the corresponding inflationary potentials at level $N>1$. The phenomenology of this class of models provides targets for ground-based CMB experiments in the immediate future. In the framework of our models we also discuss the status of the quantum gravity conjectures that have been formulated in the context of the swampland.
