Bounds on the Nonminimal Coupling of the Higgs Boson to Gravity

TL;DR

This paper establishes the first upper limit on the Higgs boson's non-minimal coupling to gravity, using recent collider data to constrain its possible strength.

Contribution

It provides the first bound on the Higgs non-minimal coupling to gravity based on experimental collider data.

Findings

Non-minimal coupling is less than 2.6×10^15.

First experimental bound on Higgs-gravity coupling.

Implications for Higgs physics and gravity theories.

Abstract

We derive the first bound on the value of the Higgs boson non-minimal coupling to the Ricci scalar. We show that the recent discovery of the Higgs boson at the Large Hadron Collider at CERN implies that the non-minimal coupling is smaller than $2.6\times 10^{15}$.
