Abstract

Based on extended SU(2)1×SU(2)2×U(1)XSU(2)_1 \times SU(2)_2 \times U(1)_\text{X} gauge groups, G(221)G(221) models predict the existence of an additional heavy gauge boson WW' and of a heavy charged Higgs boson H±H^\pm. Within this model we calculate the coupling of the WW' to (h,H±)(h,H^{\pm}), where hh can be identified with the Standard Model Higgs boson discovered recently at LHC. Using a phenomenological constraint on the ratio of the symmetry breaking scales in G(221)G(221) models, the WhH±W' \to hH^{\pm} decay width and the (h,H±)(h,H^{\pm}) production cross section via an intermediate WW' in pppp collisions at s=8\sqrt{s} = 8 TeV are calculated. Fiducial cross sections obtained with G(221)G(221) models for several final states are compared with recent results in searches for supersymmetry at LHC published by the ATLAS Collaboration.
