论文摘要
有许多单场通货膨胀模型与最近的Planck 2018测量频谱指数$ n_s $和张量表与标准比率$ r $ r $一致。尽管与观察数据达成了很好的一致性，其中一些模型的某些模型遭受了未注明的电位，这些电位会在通货膨胀结束后不久就会产生崩溃的宇宙。在本文中，我们表明，如何选择纠正通货膨胀结束的行为潜力可能会对模型的通货膨胀预测产生重大影响，特别是在四分之一的山顶和辐射校正的希格斯通货膨胀的情况下。
There are many single field inflationary models that are consistent with the recent Planck 2018 measurements of the spectral index $n_s$ and tensor-to-scalar ratio $r$. Despite good agreement with observational data some of these models suffer from having unregularized potentials which would produce a collapsing universe shortly after the end of inflation. In this paper we show that how one chooses to correct the behaviour potential towards the end of inflation can have a significant effect on the inflationary predictions of the model, specifically in the case of quartic hilltop and radiatively corrected Higgs inflation.
