Four leptons production in e-e+ collisions from 3-3-1 model

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
