摘要：
New physics models predict the possibility of extra neutral gauge bosons (Z') associated with an extra U(1)' gauge symmetry. We study the couplings of the Higgs boson to the Z boson and Z' boson predicted by the new physics models. Since there is stringent limit on the Z' boson mass from the Z' --> l(+)l(-) channel at the LHC experiments, we use two benchmark models: the leptophobic Z'(LP) which has no couplings with leptons and the eta Z'(eta) which has small couplings with fermions. The couplings of the Z' boson to quarks can also be investigated through the Z' q (q) over bar interactions. The accessible ranges of the parameter space have been searched for processes pp --> HZX and pp --> HHZX at the LHC with root s = 14 TeV. Copyright (C) EPLA, 2014
