Description
We consider different types of single field inflationary models such as Higgs inflation-types and the attractors models. We discuss their unitarity and renormalizability properties. Once quantum corrections are considered, new physics is demanded. As a matter of fact, to consistently connect the low and high energy regimes of the effective field theories (described in terms of Standard model and inflationary parameters respectively), some threshold corrections are needed. This raises the question: how are the predictions sensitive to the required UV completion?
We show under which circumstances the observables predicted by the model are insensitive to the UV completion.
