Neutral 3-3-1 Higgs Boson Through $e^{+} e^{-} Collisions
  In this work we present an analysis of production and signature of neutral Higgs bosons $H_2^0$ in the version of the 3-3-1 model containing heavy leptons at the ILC (International Linear Collider) and CLIC (Cern Linear Collider). The production rate is found to be significant for the direct production of $e^{+} e^{-} \rightarrow H_{2}^{0} Z$. We also studied the possibility to identify it using their respective branching ratios.
