Abstract
We study the process 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} and ) and t-channel electron exchange. We evaluate the number of events for an extra neutral gauge boson mass 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 for the process. From our analysis we conclude that our results give clear signals for physics beyond the Standard Model in e e colliders.
