Standard Model & Cosmology have common thing - Fundamental Scalar Field. In SM, it is called Higgs and in Cosmology, it is called Inflaton. The most natural thing that we can think of is they are same - Higgs-Inflaton! But it's not scientific to leave it as a hypothesis, so we need to shape our model. To match experimental results, we should use Strong Non-minimal coupling of Higgs-Inflaton to gravity. So, in this paper we will cover the Higgs-Inflaton as main topic and will actually match the experimental results. Of course, I will review some basic background knowledge before that. This paper is based on \citet{Steinwachs_2014} & \citet{Hamada_2015}.
