Neutral Higgs bosons in the SU(3)_(L)otimesU(1)_(N) model

The SU(3)$_L\otimesU(1)_N$ electroweak model predicts new Higgs bosons beyond the one of the standard model. In this work we investigate the signature and production of neutral SU(3)$_L\otimesU(1)_N$ Higgs bosons in the $e^-e^+$ Next Linear Collider (NLC) and in the CERN Linear Collider (CLIC). We compute the branching ratios of two of the SU(3)$_L\otimesU(1)_N$ neutral Higgs bosons and study the possibility to detect them and the $Z^\prime$ extra neutral boson of the model.
