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., Comment: 15 pages, 3 figures. arXiv admin note: substantial text overlap with arXiv:hep-ph/0506154, arXiv:1311.0845, arXiv:1205.4042

We studied the production and signatures of doubly charged Higgs bosons in the process $��e^- \rightarrow H^{--}E^+$, where $E^+$ is a heavy lepton, at the $e^-e^+$ International Linear Collider (ILC) and CERN Linear Collider (CLIC). The intermediate photons are given by the Weizs$\ddot{a}$cker-Williams and laser backscattering distributions. We found that significant signatures are obtained by bremsstrahlung and backward Comptom scattering of laser. A clear signal can be obtained for doubly charged Higgs bosons, doubly charged gauge bosons and heavy leptons.

We present an analysis of production and signature of neutral Higgs bosons on the version of the 3-3-1 model containing heavy leptons at the Large Hadron Collider (LHC). The production rate is found to be significant with a clear signature ($\sqrt{s}=14$) TeV, showing that these scalars can be detected in this accelerator. We also studied the possibility to identify them using their respective branching ratios. Cross section are given for two collider energies, $\sqrt{s} =$ 8 TeV and 14 TeV. Event rates and significances are discussed for two possible values of integrated luminosity, 10 fb$^{-1}$ and 300 fb$^{-1}$., Comment: 27 pages 10 figures

We have studied the branching ratios of doubly charged Higgs bosons at the LHC using a version of the SU(3)$_L\otimesU(1)_N$ electroweak model. At the end of this work we have made a very simple plotting comparating the total cross section of this model using Drell-Yan, gluon-gluon fusion and Left-right symmetric model., Comment: Talk given at 18th International IUPAP Conference on Few-Body Problems in Physics (FB18), Santos, Sao Paulo, Brazil, 21-26 Aug 2006

We investigate the production and signatures of a single, pair of heavy-exotic leptons via the electron-positron induced process and a pair of heavy exotic leptons via the Drell-Yan process at the CERN Large Hadron Collider (LHC). We show that the cross-section for the case of the production of heavy pair exotic leptons are competitive with the ones for the single production of exotic leptons. We also exhibit some kinematical distributions., Comment: 21 pages, plain LaTex, 9 eps figs

We study the signals for composite vector leptoquarks in $e^+ e^-$ colliders (LEP II, NLC, and CLIC) through their effects on the production of jet pairs, as well as their single and pair productions. We also analyze their production in $��e$ and $����$ collisions., revtex, 17 pages and 8 figures (available upon request), IC/92/156
