Sumario:A search for a charged Higgs boson, H<sup>±</sup>, decaying to a W<sup>±</sup> boson and a Z boson is presented. The search is based on 20.3 fb<sup>-1</sup> of proton-proton collision data at a center-of-mass energy of 8 TeV recorded with the ATLAS detector at the LHC. The H<sup>±</sup> boson is assumed to be produced via vector-boson fusion and the decays W<sup>±</sup>→qq′¯ and Z→e<sup>+</sup>e<sup>-</sup>/μ<sup>+</sup>μ<sup>-</sup> 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<sup>±</sup> 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<sup>±</sup> boson times its branching fraction to W<sup>±</sup>Z. The limits are compared with predictions from the Georgi-Machacek Higgs triplet model.
