Description
Despite the recent Nobel prize, because of the gravity of the issue of actual source of EWSB and mass generation, we consider (deferring discussion of phenomenology till later) the path of dynamical EWSB via strong Yukawa coupling lambda_Q. We build up a "bootstrap" mechanism from an empirical basis with strong lambda_Q as source of mass generation: the Goldstone boson in the loop is self-consistent with dynamical chiral/EW symmetry breaking, which we demonstrate by numerically solving our dynamical "gap equation". Curiously, the presence of a Higgs scalar would raise lambda_Q tremendously. From scale invariance of our "empirical" gap eq.,the setup could still be viable, iff the observed boson is in fact a dilaton. To exclude this possility beyond doubt, we need a convincing VBF and VH analysis, which is only possible with 2015 data. We briefly discuss a possible fascinating phenomena of heavy QQ(bar) "fireball" annihilation, and conjecture whether the old Fermi-Yang model can be realized along a non-QCD path. Connections with Flavor physics and CP violation would also be briefly touched.
