论文摘要
我们将两场混合膨胀作为一种有效的现场理论，用于低尺度膨胀，以亚平晶量表范围范围。我们专注于Stewart的原型模型，因为它允许进行红色频谱倾斜，这仍然适合当前数据。我们描述了当前CMB测量所施加的该模型的约束。然后，我们探索该模型对量子校正的稳定性。我们发现，对于相关，边际和至少一组无关的操作员集，需要一些其他机制才能使该模型从量子场理论和量子引力稳定下稳定。我们通过意识到标量为紧凑的轴偶至4美元的田地强度，并概述了可能的机制，并概述了双重理论中强大的动力学能够支持自然混合膨胀。
We revisit two-field hybrid inflation as an effective field theory for low-scale inflation with sub-Planckian scalar field ranges. We focus on a prototype model by Stewart because it allows for a red spectral tilt, which still fits the current data. We describe the constraints on this model imposed by current CMB measurements. We then explore the stability of this model to quantum corrections. We find that for relevant, marginal, and at least a finite set of irrelevant operators, some additional mechanism is required to render the model stable to corrections from both quantum field theory and quantum gravity. We outline a possible mechanism by realizing the scalars as compact axions dual to massive $4$-form field strengths, and outline how natural hybrid inflation may be supported by strong dynamics in the dual theory.
