We reexamine recent claims that Einstein-frame scattering in the Higgs inflation model is unitary above the cut-off energy Λ ≃ Mp/ξ. We show explicitly how unitarity problems arise in both the Einstein and Jordan frames of the theory. In a covariant gauge they arise from non-minimal Higgs self-couplings, which cannot be removed by field redefinitions because the target space is not flat. In unitary gauge, where there is only a single scalar which can be redefined to achieve canonical kinetic terms, the unitarity problems arise through non-minimal Higgs-gauge couplings.

- Stabilization of the electroweak vacuum by a scalar threshold effect (2012, background): “However, due to the same large non-minimal coupling, the unitarity cutoff [47–50] becomes ΛSM = MPl/ξ which is not only much lower than the Planck scale but also lower than the field scales at which the inflationary plateau develops.”
- Superconformal symmetry, NMSSM, and inflation (2010, background): “However, it was suggested in [34] that “the apparent generation of the new physics is an artifact of considering only two terms of the expansion when all terms are important”.”
- Higgs boson mass and new physics (2012, background): “One must note, that simple scale analysis leads to the unitarity violation in the Higgs inflation below the Planck energy scale [56–59].”
- On inflation with non-minimal coupling (2010, background): “Various attempts have been made at addressing whether quantum corrections spoil the validity of these non-minimal models of inflation due to the ξφ2R term; see [6, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28].”
