  We present an inflationary model in which the Standard Model Higgs doublet
field with non-minimal coupling to gravity drives inflation, and the effective
Higgs potential is stabilized by new physics which includes a dark matter
particle and right-handed neutrinos for the seesaw mechanism. All of the new
particles are fermions, so that the Higgs doublet is the unique inflaton
candidate. With central values for the masses of the top quark and the Higgs
boson, the renormalization group improved Higgs potential is employed to yield
the scalar spectral index $n_s \simeq 0.968$, the tensor-to-scalar ratio $r
\simeq 0.003$, and the running of the spectral index $\alpha=dn_s/d \ln k
\simeq -5.2 \times 10^{-4}$ for the number of e-folds $N_0=60$ ($n_s \simeq
0.962$, $r \simeq 0.004$, and $\alpha \simeq -7.5 \times 10^{-4}$ for
$N_0=50$). The fairly low value of $r \simeq 0.003$ predicted in this class of
models means that the ongoing space and land based experiments are not expected
to observe gravity waves generated during inflation.
