We study the process e−+e+→e++e++e−+e− for ILC and CLIC energy regimes, in the minimal 3–3–1 model framework. The main contributions, for the production of two bileptons each one decaying into two same-sign leptons, come from s-channel annihilation (via γ,Z and Z′) and t-channel electron exchange. We evaluate the number of events for an extra neutral gauge boson mass MZ′ in the range 1 TeV to 3 TeV. We compare some distributions from 3–3–1 model with the Standard Model background in order to extract a possible signature of the contribution of bilepton and Z′ for the process. From our analysis we conclude that our results give clear signals for physics beyond the Standard Model in e−e+ colliders.
