Higgs sector of the Standard model (SM) is replaced by the gauge SU(3)f quantum flavor dynamics (QFD) with one parameter, the scale Λ. Anomaly freedom of QFD demands extension of the fermion sector of SM by three sterile right-handed neutrino fields. Poles of fermion propagators with chirality-changing self-energies Σ(p2) spontaneously generated by QFD at strong coupling define: (1) Three sterile-neutrino Majorana masses MfR of order Λ. (2) Three Dirac masses mf, degenerate for ef, νf, uf, df in family f, exponentially small with respect to Λ. Goldstone theorem implies: All eight flavor gluons acquire masses of order MfR. W and Z bosons acquire masses of order ∑ mf, the effective Fermi scale. Composite 'would-be' Nambu-Goldstone bosons have their 'genuine' partners, the composite Higgs particles: The SM-like Higgs h and two new Higgses h3 and h8, all with masses at Fermi scale; three Higgses χi with masses at scale Λ. Large pole-mass splitting of charged leptons and quarks in f is arguably due to full QED Σ(p2)-dependent fermion-photon vertices enforced by Ward-Takahashi identities. The argument relies on illustrative computation of pole-mass splitting found non-analytic in fermion electric charges. Neutrinos are the Majorana particles with seesaw mass spectrum computed solely by QFD. Available data fix Λ to, say, Λ∼ 1014 \rm GeV.
