最近的宇宙微波背景观测似乎有力地支持了早期宇宙中暴胀时代的存在。然而，不幸的是，人们似乎只知道少数与粒子物理学密切相关的现实通货膨胀情景。具有惰性双态暗物质的辐射中微子质量模型是解决当前标准模型无法解释的实验问题的一个有前途的模型。为了使模型包含通货膨胀，我们将其扩展为具有特定势的复杂标量场。这个标量可能与 TeV 规模的中微子质量产生以及暴胀密切相关。我们表明，即使暴胀在暴胀过程中采用亚普朗克值，CMB 观测结果所支持的暴胀也可以实现。
The existence of the inflationary era in the early Universe seems to be strongly supported by recent CMB observations. However, only a few realistic inflation scenarios which have close relation to particle physics seem to have been known unfortunately. The radiative neutrino mass model with inert doublet dark matter is a promising model for the present experimental issues which cannot be explained within the standard model. In order to make the model include inflation, we extend it by a complex scalar field with a specific potential. This scalar could be closely related to the neutrino mass generation at a TeV scale as well as inflation. We show that the inflation favored by the CMB observations could be realized even if inflaton takes sub-Planck values during inflation.
