Does Planck really rule out monomial inflation?

Understand

We consider the modifications of monomial chaotic inflation models due to radiative corrections induced by inflaton couplings to bosons and/or fermions necessary for reheating.

To the lowest order, ignoring gravitational corrections and treating the inflaton as a classical background field, they are of the Coleman-Weinberg type and parametrized by the renormalization scale $\mu$.
In cosmology, there are not enough measurements to fix $\mu$ so that we end up with a family of models, each having a slightly different slope of the potential.
We demonstrate by explicit calculation that within the family of chaotic $\phi^2$ models, some may be ruled out by Planck whereas some remain perfectly viable.
