要保护暴胀势能不受量子修正的影响，通常需要对称性来限制暴胀子与其他扇区的耦合形式。我们将探讨这些限制如何影响UV完成模型中的再加热。特别是，我们看看如何再加热时发生通货膨胀是由封闭的字符串，使用N-flation作为一个例子。我们发现，耦合的暴胀优先的标准模型是困难的，隐藏的部门通常被重新加热。观测约束仅满足一小部分模型。在一些工作模型中，隐藏扇区中的相对论遗迹提供了质量从keV到PeV的暗物质候选者，更轻的质量是首选。
Protecting the inflationary potential from quantum corrections typically requires symmetries that constrain the form of couplings of the inflaton to other sectors. We will explore how these restrictions affect reheating in models with UV completions. In particular, we look at how reheating occurs when inflation is governed by closed strings, using N-flation as an example. We find that coupling the inflaton preferentially to the standard modelis difficult, and hidden sectors are typically reheated. Observational constraints are only met by a fraction of the models. In some working models, relativistic relics in the hidden sector provide dark matter candidates with masses that range from keV to PeV, with lighter masses being preferred.
