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 140 GeV 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 125 GeV to 140 GeV in the case of relatively light gauginos, and 120 GeV to 135 GeV 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.
