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 y, Z and Z) and t-channel electron exchange. We evaluate the number of events for an extra neutral gauge boson mass M-Z' 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. (c) 2005 Elsevier B.V. All rights reserved.
