Probing the Z′ resonance and the Higgs boson production and decay in a SU(3)L⊗U(1)N model at future e+e- colliders

We study the phenomenology of the Z′ resonance as well as of the light and heavy Higg boson production and decay in the framework of the SU(3)L⊗U(1)N\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ SU(3)_{L}\bigotimes U(1)_{N}$\end{document} electroweak model at future e+e-\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ e^{+}e^{-}$\end{document} linear colliders, such as the ILC and CLIC.
