  We propose a new dynamics of the electroweak symmetry breaking in a
classically scale invariant version of the standard model. The scale invariance
is broken by the condensations of additional fermions under a strong coupling
dynamics. The electroweak symmetry breaking is triggered by negative mass
squared of the elementary Higgs doublet, which is dynamically generated through
the bosonic seesaw mechanism. We introduce a real pseudo-scalar singlet field
interacting with additional fermions and Higgs doublet in order to avoid
massless Nambu-Goldstone bosons from the chiral symmetry breaking in a strong
coupling sector. We investigate the mass spectra and decay rates of these
pseudo-Nambu-Goldstone bosons, and show they can decay fast enough without
cosmological problems. We further evaluate the energy dependences of the
couplings between elementary fields perturbatively, and find that our model is
the first one which realizes the flatland scenario with the dimensional
transmutation by the strong coupling dynamics. Similarly to the conventional
flatland model with Coleman-Weinberg mechanism, the electroweak vacuum in our
model is meta-stable.
