Query: Higgs-portal assisted Higgs inflation with a sizeable tensor-to-scalar
  ratio   We show that the Higgs portal interactions involving extra dark Higgs field
can save generically the original Higgs inflation of the standard model (SM)
from the problem of a deep non-SM vacuum in the SM Higgs potential.
Specifically, we show that such interactions disconnect the top quark pole mass
from inflationary observables and allow multi-dimensional parameter space to
save the Higgs inflation, thanks to the additional parameters (the dark Higgs
boson mass $m_{\phi}$, the mixing angle $\alpha$ between the SM Higgs $H$ and
dark Higgs $\Phi$, and the mixed quartic coupling) affecting RG-running of the
Higgs quartic coupling. The effect of Higgs portal interactions may lead to a
larger tensor-to-scalar ratio, $0.08 \lesssim r \lesssim 0.1$, by adjusting
relevant parameters in wide ranges of $\alpha$ and $m_{\phi}$, some region of
which can be probed at future colliders. Performing a numerical analysis we
find an allowed region of parameters, matching the latest Planck data.
