Description

Models of quark-lepton substructure with composite W- and Z-bosons predict the existence of additional heavy vector bosons. We study a 15-plet of V-bosons which arise in a class of preon models with global Pati-Salam SU(4) invariance. An analysis of the weak interaction current-current lagrangian yields the V-masses as functions of sin2thetasub(W), Msub(W) and Msub(Z). Furthermore, a non-vanishing C-parameter for neutral currents is predicted. The new vector bosons are expected to be heavier than proportional 500 GeV. (orig.)
