Query: Vectorlike $W^\pm$-boson coupling at TeV and third family fermion masses   In the third fermion family and gauge symmetry of the Standard Model, we
study the quark-quark, lepton-lepton and quark-lepton four-fermion operators in
an effective theory at high energies. These operators have nontrivial
contributions to the Schwinger-Dyson equations for fermion self-energy
functions and the $W^\pm$-boson coupling vertex. As a result, the top-quark
mass is generated via the spontaneous symmetry breaking of $\langle\bar t t
\rangle$-condensate and the $W^\pm$-boson coupling becomes approximately
vectorlike at TeV scale. The bottom-quark, tau-lepton and tau-neutrino masses
are generated via the explicit symmetry breaking of $W^\pm$-contributions and
quark-lepton interactions. Their masses and Yukawa couplings are functions of
the top-quark mass and Yukawa coupling. We qualitatively show the hierarchy of
fermion masses and Yukawa couplings of the third fermion family. We also
discuss the possible collider signatures due to the vectorlike
(parity-restoration) feature of $W^\pm$-boson coupling at high energies.
