  Constituent quark masses can be determined quite well from experimental data
in several ways and one can obtain fairly accurate values for all six $m_q$.
The strong quark-meson coupling $g=2\pi /\sqrt{3}$ arises from the quark-level
linear $\sigma$ model, whereas $e$ and $\sin\theta_w$ arise from weak
interactions when the heavy $M_W$ and $M_Z$ are regarded as resonances in
analogy with the strong KSFR relation. The Higgs boson mass, tied to null
expectation value of charged Higgs components, is found to be around 317 GeV.
Finally, the experimental CPV phase angle $\delta$ and the three CKM angles
$\Theta_c, \Theta_2, \Theta_3$ are successfully deduced from the 6 constituent
quark masses following Fritzsch's approach.
