Higgs mass and inflation

Abstract
We show that the standard-model Higgs boson mass m_h is correlated with the spectral index of density perturbation n_s in the inflation scenario with the inflaton being identified with the B-L Higgs boson. The Higgs boson mass ranges from m_h ~ 120GeV to 140GeV for n_s ~ 0.95 - 0.96. In particular, as n_s approaches to 0.96, the Higgs mass is predicted to be in the range of 125GeV to 140GeV in the case of relatively light gauginos, and 120GeV to 135GeV in the case where all SUSY particle masses are of the same order. This will be tested soon by the LHC experiment and the Planck satellite. The relation is due to the PeV-scale supersymmetry required by the inflationary dynamics. We also comment on the cosmological implications of our scenario such as non-thermal leptogenesis and dark matter.
