Abstract

We study the process e+e+e++e++e+ee^- + e^+ \to 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 ({\it via} γ,Z\gamma, Z and Z{Z^\prime}) and t-channel electron exchange. We evaluate the number of events for an extra neutral gauge boson mass MZM_{{Z^\prime}} 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{Z^\prime} for the process. From our analysis we conclude that our results give clear signals for physics beyond the Standard Model in e^- e+^+ colliders.
