The possibility of discovering new boson in e[sup -]e[sup -],μ[sup -]μ[sup -],e[sup -]μ[sup -] colliders.

Several left-right asymmetries in Møller (electron-electron), muon-muon and electron-muon scattering are considered in the context of the electroweak standard model and in a model with SU(3)[sub C] ⊗ SU(3)[sub L] ⊗ U(1)[sub Y] gauge symmetry at tree level in collider experiments. We show that these asymmetries are very sensitive to a doubly charged vector bilepton in the case of ee and μμ colliders and to an extra Z′ neutral vector boson contribution in e[sup -] μ[sup -] collider.
