Composite photon and W-+/-,Z(0) vector bosons from a top-condensation model at fixed upsilon=247 GeV

Starting from the historical Fermi four-fermion low-energy effective electr oweak interactions Lagrangian for the third generation of quarks, augmented by an NJL type interaction responsible for dynamical symmetry breaking and heavy quark mass generation, and fixing the scalar (Higgs) field v.e.v. at nu = 247 GeV, we show that: (1) heavy quark bound states eg with quantum n umbers of the W (+/-) bosons exist for arbitrarily weak (positive) vector c ouplings G(F), so long as the quark mass is sufficiently large; (2) a massi ve composite neutral vector boson (Z(0)) appears; (3) a massless composite parity-conserving neutral vector boson (gamma) appears, the composite Higgs -Kibble ghosts decouple from the quarks and other particles, the longitudin al components of the vector boson propagators vanish, as GF --> G(F)(expt.) = 1/(root 2 nu(2)), which also implies that the cutoff Lambda --> infinity . Thus, the Fermi interaction model is equivalent to a locally gauge invari ant theory but with definite values of coupling constants and masses. The m odel discussed here was chosen for illustrative purposes and is not equival ent to the Standard Model. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
