Constituent Quark Masses and the Electroweak Standard Model

Abstract

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 $g=2π/\sqrt{3}$ arises from the quark-level linear $σ$ model, whereas $e$ and $\sinθ_w$ 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 $δ$ and the three CKM angles $Θ_c, Θ_2, Θ_3$ are successfully deduced from the 6 constituent quark masses following Fritzsch's approach.
