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 $805\mathrm{GeV}\lesssim m_{\mathrm{DM}}\lesssim 1220\mathrm{GeV}$ for the DM mass, $1.05\times 10^{14}\mathrm{GeV}\lesssim M_R\lesssim 2.04\times 10^{14}\mathrm{GeV}$ for the right-handed neutrino mass, and $8.42\lesssim \xi \lesssim 12.4$ for the non-minimal coupling within $m_H=125.6\pm 0.35\mathrm{GeV}$ for the Higgs and $M_t=173.34\pm 0.76\mathrm{GeV}$ for the top masses.
