  Yang-Mills-Higgs theory is quite a remarkable theory in that it shows very
different behaviors without phase transitions. It is dominated by the
Brout-Englert-Higgs mechanism in some domain of the phase diagram, while it is
essentially QCD-like in another. It is expected that albeit there is no
qualitative difference, there are substantially quantitative differences
throughout the spectrum. This is investigated using lattice theory for the case
of the scalar singlet channel for more than a hundred different points in the
phase diagram. It is found that the results deviate partly substantially from
the expectations in some cases, but in others justify the picture of a weakly
interacting theory - even in cases of rather strong interactions at the
ultraviolet cutoff.
