论文摘要

在引力的常规度量公式中,Higgs通货膨胀模型违反了Higgs散射的Electroweak真空度的单位性,以$λ\ sim m_ {pl}/ξ$,其中$ξ\ sim 10^4 $是higgs to higgs to riccici calcci scalar to riccici calcci scalar的非密西西比性。在Palatini公式中,通常认为$λ\ sim m_ {pl}/\ sqrtT配$,其中$ξ\ sim 10^{9} $。在这里,我们重新考虑了Palatini配方中的Electroweak真空中的单位性违反。我们认为,帕拉蒂尼(Palatini)在palatini散射的希格斯(Higgs)在palatini散射的electroweak真空中的非最低耦合标准模型在普朗克尺度以下的能量下没有违规。在这种情况下,帕拉蒂尼·希格斯(Palatini Higgs)的通货膨胀完全保留了单位性,并且在量子重力变得重要的那些能量上都保持一致。如果是真的,这将暗示Palatini Higgs通货膨胀比公制Higgs通货膨胀具有显着优势。

In the conventional metric formulation of gravity, the Higgs Inflation model violates unitarity in the electroweak vacuum in Higgs scattering at the energy scale $Λ\sim M_{Pl}/ξ$, where $ξ\sim 10^4$ is the non-minimal coupling of the Higgs to the Ricci scalar. In the Palatini formulation it is commonly believed that $Λ\sim M_{Pl}/\sqrtξ$, where $ξ\sim 10^{9}$. Here we reconsider unitarity violation in the electroweak vacuum in the Palatini formulation. We argue that there is no unitarity violation in Higgs scattering in the Palatini non-minimally coupled Standard Model in the electroweak vacuum at energies below the Planck scale. In this case Palatini Higgs Inflation completely conserves unitarity and is consistent at all energies up to those at which quantum gravity becomes important. If true, this would imply that Palatini Higgs Inflation has a significant advantage over metric Higgs Inflation.
