Web7 de dez. de 2024 · Abstract. Higgs inflation is known to be a minimal extension of the Standard Model allowing for the description of the early Universe inflation. This … WebPseudoscalars appear frequently in particle spectra. They can be light if they appear as pseudo-Goldstone bosons from some spontaneously broken global symmetries with the decay constant f. Since any global symmetry is broken at least by quantum gravitational effects, all pseudoscalars are massive. The mass scale of a pseudoscalar is determined …

It is an implicit assumption of the Higgs inflation that such an extension does not affect the result qualitatively, that is, the Wilson coefficients of the higher order terms are sufficiently smaller than 1/ξ1𝜉1/\xi1 / italic_ξ.
WebTwo Higgs doublet model in the light of muon g-2 anomaly，佐藤 亮介，Asian Linear Collider Workshop(ALCW2015)，2015年04月21日; Inflation, leptogenesis, neutrino masses and PeV neutrinos from right-handed neutrino dark matter，佐藤 亮介，素粒子物理学の進展 2014，2014年07月29日 Web23 de fev. de 2024 · We find that just before the Higgs as inflaton enters the flat region of the potential the usual slow-roll conditions are violated. This leads to “overshooting” behavior, which in turn strongly enhances scalar curvature perturbations because of the excitation of entropic (non-adiabatic) perturbations.
