标题： Electroweak metastability and Higgs inflation

摘要： 在高能下外推标准模型希格斯势，我们研究电弱和普朗克尺度极小值之间的势垒。 势垒是通过取相关实验输入的中心值来产生的，即强耦合常数和顶夸克及希格斯质量。 然后我们通过包括与引力的非最小耦合来扩展标准模型，并探讨希格斯膨胀模型的物理现象。 我们指出，即使在标准模型中为亚稳态的配置，如果非最小耦合足够大以在势垒以下场值处平坦化希格斯势，则对于膨胀来说是可行的；我们发现所需的非最小耦合值小于传统希格斯膨胀情景所需的值（传统情景依赖于稳定的标准模型希格斯势，没有任何势垒）；此外，允许的顶夸克质量值略高于传统情景所需的值。 显示英文摘要

摘要： Extrapolating the Standard Model Higgs potential at high energies, we study the barrier between the electroweak and Planck scale minima. The barrier arises by taking the central values of the relevant experimental inputs, that is the strong coupling constant and the top quark and Higgs masses. We then extend the Standard Model by including a non-minimal coupling to gravity, and explore the phenomenology of the Higgs inflation model. We point out that even configurations that would be metastable in the Standard Model, become viable for inflation if the non-minimal coupling is large enough to flatten the Higgs potential at field values below the barrier; we find that the required value of the non-minimal coupling is smaller than the one needed for the conventional Higgs inflation scenario (which relies on a stable Standard Model Higgs potential, without any barrier); in addition, values of the top mass which are slightly larger than those required in the conventional scenario are allowed.
