Neutral 3-3-1 Higgs Bosons at LHC

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$^{-1}$.
