Query: Multi-Higgs Production and Unitarity in Vector-Boson Fusion at Future
  Hadron Colliders   We study multi-Higgs final states in vector boson fusion (VBF) processes at
the LHC and at future proton-proton colliders, focusing on the prospects for
measurements at 27 TeV and at 100 TeV. We use an effective Lagrangian which
includes higher-dimensional operators in the mass eigenstates which are
relevant to VBF processes and relate this to specific parameterizations and
models for new physics in the Higgs sector. We derive theoretical constraints
on the parameter space from the unitarity of $2\to n$ scattering amplitudes and
apply the results to $V V \to hh$ and $h h h$ processes, where $V=W,Z$. As a
result, we present constraints on differential distributions as appropriate to
the study of $V V \to hh$ and $h h h$ processes.
