Abstract

We show that the dominant channel proposed for the determination of the Higgs boson trilinear coupling, pp→HH+X via gluon fusion, exhibits an interference structure that is independent of the collider energy for collider energies in the range 8  TeV≤s≤100  TeV and is almost maximally destructive. This insensitivity to the collider energy remains approximately true for a variety of other two Higgs production mechanisms although the magnitude of the interference varies widely.
