Abstract
The novel feature of a Higgs-triplet representation is a nonzero tree-level coupling of H + W - Z, which is absent in all Higgs-doublet models. We study the associated production of a singly-charged Higgs boson of the Higgs-triplet representation with a W or Z boson at hadron colliders, followed by the H + → W + Z decay. We find that the 2l + 4j final state gives an interesting level of signal with a negligible background, plus it allows a full mass reconstruction of the charged-Higgs boson. The cover range of the charged-Higgs mass is between 110 and 200 GeV. © SISSA/ISAS 2002.
