Composite weak vector bosons in a left-right symmetric preon model

We take the viewpoint that the standard model is a low energy effective theory among composite quarks, leptons and weak bosons in a left-right (LR) symmetric preen model with a hypercolor SU(N)(HC) gauge interaction. Starting from NJL-type interactions with global SU(2)(L)xSU(2)(R) symmetry, we construct the composite weak vector bosons from a pair of spinor preens and derive their effective interactions with quarks and leptons, which are essentially identical, at the tree-diagram level, to those in the LR symmetric gauge model. Through the process of this approach, some physical aspects of the LR gauge model are clarified.
