Search for HZZ' couplings at the LHC
Abstract
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. The couplings of the Z' boson to quarks can also be investigated through the Z'qq interactions. The accessible ranges of the parameter space have been searched for processes pp→ HZX and pp→ HHZX at the LHC with s=14 TeV.
