  We investigate the scenario where the Standard Model is extended with
classical scale invariance, which is broken by chiral symmetry breaking and
confinement in a new strongly-coupled gauge theory that resembles QCD. The
Standard Model Higgs field emerges as a result of the mixing of a scalar meson
in the new strong dynamics and a massless elementary scalar field. The mass and
scalar decay constant of that scalar meson, which are generated dynamically in
the new gauge theory, give rise to the Higgs field mass term, automatically
possessing the correct negative sign by the bosonic seesaw mechanism. Using
analogy with QCD, we evaluate the dynamical scale of the new gauge theory and
further make quantitative predictions for light pseudo-Nambu-Goldstone bosons
associated with axial symmetry breaking along chiral symmetry breaking in the
new gauge theory. A prominent consequence of the scenario is that there should
be a Standard Model gauge singlet pseudo-Nambu-Goldstone boson with mass below
220GeV, which couples to two electroweak gauge bosons through the
Wess-Zumino-Witten term, whose strength is thus determined by the dynamical
scale of the new gauge theory. Other pseudo-Nambu-Goldstone bosons, charged
under the electroweak gauge groups, also appear. Concerning the theoretical
aspects, it is shown that the scalar quartic coupling can vanish at the Planck
scale with the top quark pole mass as large as 172.5GeV, realizing the flatland
scenario without being in tension with the current experimental data.
