标题： Light inflaton completing Higgs inflation

摘要： 我们研究了标准模型（SM）的扩展模型，其中包含一个轻度膨胀子，该模型解决了希格斯膨胀中的单位性问题和真空不稳定性问题。 膨胀子与引力的线性非最小耦合导致膨胀子与引力子之间存在显著的动力学混合，从而使得微扰单位性可以恢复到普朗克尺度。 我们展示了此模型中单位性标度与膨胀观测值之间的相关性，并讨论了有效希格斯膨胀的出现方式。 显示英文摘要

摘要： We consider the extension of the Standard Model (SM) with a light inflaton where both unitarity problem in Higgs inflation and vacuum instability problem are resolved. The linear non-minimal coupling of the inflaton to gravity leads to a significant kinetic mixing between the inflaton and the graviton such that perturbative unitarity is restored up to Planck scale. We show the correlation between unitarity scale and inflationary observables in this model and discuss how the effective Higgs inflation appears.
