Abstract:

LHC experiments discovered Higgs particle, and its mass is about 126 GeV. Estimating quantum corrections (by use of renormalization group equation analyses), 126 GeV Higgs mass (with 173 GeV top quark mass) implies that Higgs potential vanishes around the Planck scale. Is it just an accident or not? I take a standing point that it is not the accident, and focus on the fact that precise analyses show the Higgs potential at the Planck scale is not exactly vanished. I also focus on the standard model does not have a dark matter candidate nor induce tiny neutrino mass. I will show the vanishing Higgs potential at the Planck can be achieved by introducing a dark matter and by explaining tiny neutrino mass. It predicts the dark matter mass is 8.5 ×10^2 GeV ~ 1.4 ×10^3 GeV and right-handed neutrino mass is 6.3 ×10^13 GeV ~ 1.6 (1.2)×10^14 GeV.
