Some like it hot: R2 heals Higgs inflation, but does not cool it
Strong coupling in Higgs inflation at high energies hinders a joint description of inflation, reheating and low-energy dynamics. The situation may be improved with a proper UV completion of the model. A well-defined self-consistent way is to introduce an R2-term into the action. In this modified mod...
