概要
Abstract:
Inflation is the most plausible mechanism to resolve several
cosmological problems in the early universe. Higgs inflation
is clearly the most economical possibility. The original
Higgs inflation, however, requires quite a huge coupling
between the Higgs field and the gravity, named the
non-minimal coupling. We propose a model with a right-handed
neutrino and a Z_2 odd real scalar field, which can account
for tiny neutrino masses and the dark matter. We show that
our model gives the non-minimal coupling of around 10,
consistent with the recent Planck observation. Furthermore,
we show that the masses of the right-handed neutrino and
the dark matter are not seriously constrained by the
observed value of the tensor-to-scalar ratio.
