Description
It is known that the Higgs inflation suffers from unitarity problem due to a large non-minimal coupling of Higgs field to Ricci scalar. Recently, it has been clear that introducing a Ricci square term (R2 term) in the Higgs inflation can solve this problem, and provide its UV completion. This model known as Higgs-R2 inflation perfectly agrees with the CMB observation of the Planck result. In this talk, we discuss a supersymmetric embedding of the Higgs-R2 inflation, whcih is desired from a naturalness consideration. We investigate several conditions for the original successful inflation to be kept after supersymmetrization, and also discuss supersymmetry breaking and its phenomenological consequence.
