Abstract
A coupling of a scalar, U(1) symmetry, to the Standard Model via the Higgs portal is one of the simplest gateways to a dark sector. Yet, for masses m S ≥ m H / 2 there are few probes of such an interaction. In this note we evaluate the sensitivity of di-Higgs production at the LHC as well as at a future FCC-hh, taking into account the full momentum dependence of the process. This significantly impacts the sensitivity compared to estimates of changes in the Higgs-coupling based on the effective potential. We also compare our findings to precision single Higgs probes such as the cross section for production at a future lepton collider, e.g. FCC-ee, as well as searches for missing energy \JJ{based signatures.
