Including the QCD effects through the Cornwall-Jackiw-Tomboulis effective potential, we establish that the correct electroweak symmetry breaking SU (2)L × U (1)Y → U (1) em occurs in this model in 1/N leading and improved ladder approximation.

For both light and heavy sector we include pseudo scalars, vectors and baryons in the Lagrangian. Heavy hadron decays are discussed as application of our formalism. The $D_s$ decay constant and the coupling constant among heavy meson, heavy vector meson and light meson are fitted from the experimental data of $D^0 \rightarrow K^- e^+\nu_e$ decay. We also point out the possibility of model independent determination of $|V_{ub}|$ from $\Lambda_b \rightarrow p l \bar \nu$ decay.
