Lower limits are calculated on the mass of an additional neutral gauge boson, Z′, suggested by the Sp (6)L⊗ U (1)Ymodel, using direct search limits at hadron collider. We found that MZ′≥ 655 GeV . The production cross-section times branching ratio of Z′ decaying into dileptons in hadronic collisions, is found to be generation dependent and can be used to distinguish the model.

We examine the possibility that heavy lepton pair production can be significantly enhanced by the existence of a new neutral gauge boson, Z’, at SSC energies. We find that in some models, the heavy lepton production cross section resulting from this mechanism exceeds that from production via other scenarios.
