论文摘要
在三种通货膨胀模型中，我们从通货膨胀期间的真空稳定性中得出了HIGGS曲面耦合的下限：二次和四分之一的混沌通货膨胀以及Starobinsky类似于Starobinsky的幂律通货膨胀。与大多数先前的研究相反，我们将哈勃速率的时间依赖性考虑到过去轻锥的几何形状和希格斯的有效潜力中，这与补充了一环曲率校正的三环重型型组的改进近似。我们发现，在所有三个模型中，下限为$ξ\ gtrsim 0.051 \ ldots 0.066 $，具体取决于顶部的夸克质量。我们还证明，在通货膨胀结束之前，真空衰减很可能发生几美元。
We derive lower bounds for the Higgs-curvature coupling from vacuum stability during inflation in three inflationary models: quadratic and quartic chaotic inflation, and Starobinsky-like power-law inflation. In contrast to most previous studies we take the time-dependence of the Hubble rate into account both in the geometry of our past light-cone and in the Higgs effective potential, which is approximated with three-loop renormalisation group improvement supplemented with one-loop curvature corrections. We find that in all three models, the lower bound is $ξ\gtrsim 0.051\ldots 0.066$ depending on the top quark mass. We also demonstrate that vacuum decay is most likely to happen a few $e$-foldings before the end of inflation.
