IS THE t QUARK RESPONSIBLE FOR THE MASS OF W AND Z BOSONS?

This is the authors' abstract. We don't add key points for this paper.

Based on the dynamical model having a large anomalous dimension γ m ≃ 2, we propose that the t quark condensate is responsible for the mass of W and Z bosons within the framework of the SU (3) C ×SU(2) L ×U(1) Y gauge theory (without Higgs) plus four-fermion interactions among quarks and leptons. This accounts for the largeness of the t quark mass m t without violating the weak-isospin relation [Formula: see text]. Quark/lepton mass matrices are obtained through the four-fermion interactions, which yields no serious flavor-changing neutral currents. The model predicts a [Formula: see text] composite scalar meson with a mass ≃2m t . A possibility for an unusual resolution of the strong CP problem is also suggested.
