Understand

With the LHC discovery of a 125 GeV Higgs-like boson, we study gravitational interaction of the Higgs boson via the unique dimension-4 operator involving Higgs doublet and scalar curvature, $\,\xi H^\dag H R\,$, with nonminimal coupling $\,\xi\,$.

This Higgs portal term can be transformed away in Einstein frame and induces gauge-invariant effective interactions in the Higgs sector.
We study the weak boson scattering in Einstein frame, and explicitly demonstrate the longitudinal-Goldstone boson equivalence theorem in the presence of $\,\xi\,$ coupling.
With these, we derive unitarity bound on the Higgs gravitational coupling $\,\xi\,$ in Einstein frame, which is stronger than that inferred from the current LHC Higgs measurements.

For this effective theory study, we do not concern with any detail of the UV dynamics above Λ UV = 𝒪 ⁡ ( 10 TeV ) \,\Lambda_{\text{UV}}=\mathcal{O}({10\,\text{TeV}})\, . There exists well-defined TeV scale quantum gravity theories on market. An explicit example is an extra dimensional scenario with compactification scale of 𝒪 ⁡ ( 10 TeV ) \,\mathcal{O}({10\,\text{TeV}})\, and the Kaluza-Klein modes will reveal themselves at energies above 𝒪 ⁡ ( 10 TeV ) \,\mathcal{O}({10\,\text{TeV}})\,
