  We study vector-boson scattering of the physical, gauge-invariant states in a
reduced standard-model setup on the lattice for various parameter sets. To this
end, the phase shift in the scalar channel is determined using a L\"uscher-type
analysis. The results can be readily interpreted in terms of the Higgs
properties and a reunitarized Fr\"ohlich-Morchio-Strocchi analysis at Born
level. The only deviation appears for a Higgs mass below the elastic threshold,
where we find a negative scattering length indicative of the bound-state nature
of the physical scalar degree of freedom. We assess the possible implications
for an experimental detection of the effect.
