Abstract
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(±)→qq' 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.

Summary
A search for a charged Higgs boson, HÆ, decaying to a WÆ boson and a Z boson is presented. The search is performed in a range of charged Higgs boson masses from 200 to 1000 GeV. The invariant mass of the two leptons and two signal jets mlljj is used to reconstruct the charged Higgs boson mass, mHÆ.
