Unitarity and predictiveness in new Higgs inflation
  In new Higgs inflation the Higgs kinetic terms are non-minimally coupled to
the Einstein tensor, allowing the Higgs field to play the role of the inflaton.
The new interaction is non-renormalizable, and the model only describes physics
below some cutoff scale. Even if the unknown UV physics does not affect the
tree level inflaton potential significantly, it may still enter at loop level
and modify the running of the Standard Model (SM) parameters. This is analogous
to what happens in the original model for Higgs inflation. A key difference,
though, is that in new Higgs inflation the inflationary predictions are
sensitive to this running. Thus the boundary conditions at the EW scale as well
as the unknown UV completion may leave a signature on the inflationary
parameters. However, this dependence can be evaded if the kinetic terms of the
SM fermions and gauge fields are non-minimally coupled to gravity as well. Our
approach to determine the model's UV dependence and the connection between low
and high scale physics can be used in any particle physics model of inflation.
