Production of the heaviest charged Higgs boson in 3-3-1 models

Abstract

We study the production cross section of the heaviest hypercharge-two Higgs boson (H ± 2 ) predicted by the 3-3-1 model. Taking into account intermediate vector bosons, including a new Z ′ neutral boson, we calculate the cross section of H ± 2 pair production at CERN-LHC hadron collider. Considering Z ′ -mass of the order of 1 TeV, we found that the cross sections decreases from 100 fb to 1 × 10 −3 fb for the H ± 2 -mass range 200 -1000 GeV. We also found that for masses below the kinematic threshold (500 GeV), the cross section splits into three branches for H
