Abstract:
Properties of resonances of quarks, leptons and gauge bosons are studied. An effective coupling of resonances to a quark or lepton is constrained by naturalness argument on the smallness of masses and anomalous magnetic moments of quarks and leptons induced by resonances. Special emphasis is laid on angular distributions in qq (or e+e-) →Z →llr via resonances. Our results are compared with those from the recently found llr events in the CERN SppS collider experiments.
