Higgs inflation and Higgs portal dark matter with right-handed neutrinos

Abstract

We investigate the Higgs inflation and the Higgs portal dark matter with the right-handed neutrino. The dark matter and the right-handed neutrino in the Higgs inflation play important roles in explaining the recent experimental results of the Higgs and top masses, and the cosmic microwave background by BICEP2 at the same time. This inflation model predicts 805 GeV ≤ mDM ≤ 1220 GeV for the DM mass, 1.05 × 1014 GeV ≤ MR ≤ 2.04 × 1014 GeV for the right-handed neutrino mass, and 8.42 ≤ ξ ≤ 12.4 for the non-minimal coupling within mH = 125.6 ‡ 0.35 GeV for the Higgs and Mt = 173.34 ‡ 0.76 GeV for the top masses.
