A Gauge Model for Extra Weak Bosons Implied by Compositeness of Quarks and Leptons

Properties of extra weak bosons are discussed in a gauge model based on SU(2)_LXU(1)_YXSU(2)‘_L. The physics of SU(2)’_L respects the duality in the Higgs and confining phases, where massive gauge bosons in the Higgs phase are equivalently represented by composite vector bosons in the confining phase below the scale of SU(2)‘_L . interactions for SU(2)’_L-singlet composites induced in the confining phase can be generated by nonlinear interactions of the four Fermi type respecting SU(2)LXU(1)Y, which create quarks, q_i^A (A=r,g,b; i=1,2), leptons, l_i, vector bosons, V_mu^(a) (a=1,2,3) and the Higgs scalar, phi, made by scalar subconstituents, c^{0,A}, and spinor subconstituents, w_i,as q.l=cw, V=(w-{bar}w){J=1} and phi=(w-{bar}w){J=0} . The physics described by these composites is equivalent to the one by SU(2)_LXU(1)_YXSU(2)'_L below the confining scale.
