Abstract
For the central values of the relevant experimental inputs, that is the strong coupling constant and the top quark and Higgs masses, the effective Higgs potential displays two minima, one at the electroweak scale and a deeper one at high energies. We review the phenomenology of the Higgs inflation model, extending the Standard Model to include a non-minimal coupling to gravity; as recently shown, even configurations that would be metastable in the Standard Model, become viable for inflation if the non-minimal coupling is large enough to flatten the Higgs potential at field values below the barrier between the minima.

Report
This note reviews the status of Higgs inflation: an extremely attractive model which may be able to reconcile the SM, Gravity as we know it, and inflation. It is well known that the viability of the model hinges on the precise value of the top quark mass.
The authors have reviewed the literature on the subject and presented up to date predictions and constraints for this model. The model - and its phenomenological analysis presented here - represent an extremely important motivation for further top quark mass studies.
The presentation is clear, with good explanations and clear plots. I can strongly recommend it for publication.
