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.

  1. Precision Unitarity Calculations in Inflationary Models

    hep-ph 2025-05 conditional novelty 7.0 of 10

    Full S-matrix unitarity calculations show the cut-off in single-field nonminimal inflation rises to about 20 M_Pl/ξ for small couplings, while multifield kinetic interactions keep the cut-off near M_Pl/ξ.

  2. Torsion induced current-scalaron coupling in Einstein-Cartan gravity

    hep-ph 2025-07 conditional novelty 6.0 of 10

    In Einstein-Cartan gravity, torsion-current couplings induce scalaron-current and scalaron Chern-Simons interactions, with explicit decay constants and a classification of their asymptotic behavior.

  3. Phenomenological Constraints on Higgs reheating

    hep-ph 2025-08 unverdicted novelty 5.0 of 10

    For Higgs-portal reheating with a light inflaton, the combination of vacuum stability, perturbativity, and LHC constraints limits the reheating temperature to between roughly 3.4e6 and 3.9e12 GeV.
