BILEPTON RESONANCE IN ELECTRON–ELECTRON SCATTERING

Theoretical backgound for bileptonic gauge bosons is reviewed, both the SU(15) GUT model and the 3-3-1 model. Mass limits on bileptons are discussed coming from e+e− scattering, polarized muon decay and muonium-antimuonium conversion. Discovery in e−e− at a linear collider at low energy (100GeV) and high luminosity (1033/cm2/s) is emphasised.
