Dynamically induced Planck scale and inflation in the Palatini
  formulation
  We study non-minimal Coleman-Weinberg inflation in the Palatini formulation
of gravity in the presence of an $R^2$ term. The Planck scale is dynamically
generated by the vacuum expectation value of the inflaton via its non-minimal
coupling to the curvature scalar $R$. We show that the addition of the $R^2$
term in Palatini gravity makes non-minimal Coleman-Weinberg inflation again
compatible with observational data.
