Non-minimally coupled quartic inflation with Coleman-Weinberg one-loop
  corrections in the Palatini formulation
  We discuss how the non-minimal coupling $\xi \phi^2 R$ between the inflaton
and the Ricci scalar affects predictions of single field inflation models in
Palatini formalism. To transition radiation dominated era, the inflaton field
$\phi$ must interact to matter fields at the end of inflation. Interactions of
the inflaton with other fields lead to radiative corrections to the
inflationary potential. These radiative corrections can be explained at leading
order by Coleman-Weinberg (CW) one-loop corrections. In this work, using two
different prescriptions debated in the literature, the effect of radiative
corrections to the potential owing to the coupling of the inflaton to bosons in
Prescription I and couplings of the inflaton to bosons and fermions in
Prescription II have been examined. We analyze the range of these coupling
parameter values for which the spectral index $n_s$ and the tensor-to-scalar
ratio $r$ are compatible with the data taken into account to the Keck
Array/BICEP2 and Planck collaborations. Finally, we also show that for all the
considered potentials the running of the spectral index $\alpha=\mathrm{d}
n_s/\mathrm{d} \ln k$ as a function of $\kappa$ for selected $\xi$ values.
