  We estimate the reach of global Higgs analyses at a 27 TeV hadron collider in
terms of Higgs couplings and in terms of a gauge-invariant effective
Lagrangian, including invisible Higgs decays and the Higgs self-coupling. The
new collider will indirectly probe new physics in the TeV range and allow for a
meaningful test of the Higgs self-coupling also embedded in a global analysis.
