Abstract
The observed value of the Higgs boson mass indicates that the Higgs potential becomes small and flat at the scale around 10(17) GeV. Having this fact in mind, we reconsider the Higgs inflation scenario proposed by Bezrukov and Shaposhnikov. It turns out that the nonminimal coupling ξ of the Higgs squared to the Ricci scalar can be smaller than 10. For example, ξ=7 corresponds to the tensor-to-scalar ratio r≃0.2, which is consistent with the recent observation by BICEP2.Year: 2014 PMID: 24996079 DOI: 10.1103/PhysRevLett.112.241301
