Higgs physics Beyond standard model Cosmology of theories beyond the SM Standard model Física Journal of High Energy Physics 2014.9 (2014): 027 reproduced by permission of Scuola Internazionale Superiore di Studi Avanzati (SISSA) We discuss a simple unitarization of Higgs inflation that is genuinely weakly coupled up to Planckian energies. A large non-minimal coupling between the Higgs and the Ricci curvature is induced dynamically at intermediate energies, as a simple ratio of mass scales. Despite not being dominated by the Higgs field, inflationary dynamics simulates the ‘Higgs inflation’ one would get by blind extrapolation of the low-energy effective Lagrangian, at least qualitatively. Hence, Higgs inflation arises as an approximate ‘mirage’ picture of the true dynamics. We further speculate on the generality of this phenomenon and show that, if Higgs-inflation arises as an effective description, the details of the UV completion are necessary to extract robust quantitative predictions This work has been partly supported by the Spanish Ministry MEC under grants FPA2013-44773-P, FPA2012-32828, and FPA2011-25948, by the Generalitat grant 2014-SGR-1450 and by the Severo Ochoa excellence program of MINECO under the grants SO-2012-0234 and SO-2012-0249.
