  The search for the weakly-coupled Higgs sector at future colliders consists
of three phases: discovery of a Higgs candidate, verification of the Higgs
interpretation of the signal, and precision measurements of Higgs sector
properties. The discovery of one Higgs boson with Standard Model properties is
not sufficient to expose the underlying structure of the electroweak symmetry
breaking dynamics. It is critical to search for evidence for a non-minimal
Higgs sector and/or new physics associated with electroweak symmetry breaking
dynamics.
