A search for a charged Higgs boson, H^(±), decaying to a W^(±) boson and a Z boson is presented. The search is based on 20.3 fb⁻¹ of proton-proton collision data at a center-of-mass energy of 8 TeV recorded with the ATLAS detector at the LHC. The H^(±) boson is assumed to be produced via vector-boson fusion and the decays W^(±) → qq̅' and Z → e⁺e⁻/μ⁺μ⁻ are considered. The search is performed in a range of charged Higgs boson masses from 200 to 1000 GeV. No evidence for the production of an H^(±) boson is observed. Upper limits of 31-1020 fb at 95% C.L. are placed on the cross section for vector-boson fusion production of an H^(±) boson times its branching fraction to W^(±) Z. The limits are compared with predictions from the Georgi-Machacek Higgs triplet model.
