轻暴胀子完成希格斯暴胀

Light inflaton completing Higgs inflation

Hyun Min Lee

摘要:

本文考虑了在标准模型中引入一个轻暴胀子的推广,其中既解决了Higgs暴胀中的么正性问题,又解决了真空不稳定性问题。暴胀子与引力的线性非最小耦合导致暴胀子与引力子之间显著的动力学混合,使得微扰么正性恢复到普朗克尺度。我们给出了该模型中幺正标度与暴胀观测量之间的关系,并讨论了有效的希格斯暴胀是如何出现的。

英文摘要:

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.
