论文摘要

基于当前的实验数据,标准模型预测宇宙的当前真空状态是可稳定的,从而通过真空气泡的成核通过真空的真空衰减速率。我们的存在意味着在我们过去的灯酮中,都不可能发生任何这样的气泡成核事件。我们考虑了标准模型以及Starobinsky通货膨胀的最小情况,使用三环重新归一化组改善了HIGGS通过一环曲率校正提高了有效的潜力。我们表明,通过通货膨胀的真空状态的存活率在非微小希格斯曲率耦合上放置了下限$ξ\ gtrsim 0.1 $,这是标准模型的最后一个未知参数。与没有希格斯融合耦合的单场通货膨胀模型中,这种结合要明显强。它也对通货膨胀结束时动态的细节敏感,因此可以通过对该时期进行更详细的研究来改进它。

Based on the current experimental data, the Standard Model predicts that the current vacuum state of the Universe is metastable, leading to a non-zero rate of vacuum decay through nucleation of bubbles of true vacuum. Our existence implies that there cannot have been any such bubble nucleation events anywhere in our whole past lightcone. We consider a minimal scenario of the Standard Model together with Starobinsky inflation, using three-loop renormalization group improved Higgs effective potential with one-loop curvature corrections. We show that the survival of the vacuum state through inflation places a lower bound $ξ\gtrsim 0.1$ on the non-minimal Higgs curvature coupling, the last unknown parameter of the Standard Model. This bound is significantly stronger than in single field inflation models with no Higgs-inflaton coupling. It is also sensitive to the details of the dynamics at the end of inflation, and therefore it can be improved with a more detailed study of that period.
