The existence of a heavy gauge boson W′ is predicted by G(221) models, with SU(2)1 × SU(2)2 × U(1)X extended gauge groups. The doublet and bi-doublet Higgs sector of G(221) models is assumed, and the breaking of the symmetry is produced in two stages. We study W′ → hH± production in p-p collisions at √s = 8 TeV. This analysis is dedicated to W′ → hH± decay channel, where h is neutral and H± is charged, and we calculate the partial width for W′ → hH± within G(221) model. We further consider the final state consisting of two same-sign leptons, MET and four jets, from which two are b-jets, arising from the decays of H± and h and compare for this channel the predictions of G(221) models with those of SUSY published by ATLAS Collaboration
