  We continue our study of Coleman-Weinberg symmetry breaking induced by a
third rank antisymmetric tensor scalar, in the context of the $SU(8)$ model we
proposed earlier. We focus in this paper on qualitative features that will
determine whether the model can make contact with the observed particle
spectrum. We discuss the mechanism for giving the spin $\frac{3}{2}$ field a
mass by the BEH mechanism, and analyze the remaining massless spin
$\frac{1}{2}$ fermions, the global chiral symmetries, and the running couplings
after symmetry breaking. We note that the smallest gluon mass matrix eigenvalue
has an eigenvector suggestive of $U(1)_{B-L}$, and conjecture that the theory
runs to an infrared fixed point at which there is a massless gluon with 3 to -1
ratios in generator components. Assuming this, we discuss a mechanism for
making contact with the standard model, based on a conjectured asymmetric
breaking of $Sp(4)$ to $SU(2)$ subgroups, one of which is the electroweak
$SU(2)$, and the other of which is a "technicolor" group that binds the
original $SU(8)$ model fermions, which play the role of "preons", into
composites. Quarks can emerge as 5 preon composites and leptons as 3 preon
composites, with consequent stability of the proton against decay to a single
lepton plus a meson. A composite Higgs boson can emerge as a two preon
composite. Since anomaly matching for the relevant conserved global symmetry
current is not obeyed by three fermion families, emergence of three composite
families requires formation of a Goldstone boson with quantum numbers matching
this current, which can be a light dark matter candidate.
