Abstract
Abstract:
A search for a heavy resonance decaying into W Z in the fully leptonic channel (electrons and
muons) is performed. It is based on proton–proton collision data collected by the ATLAS experiment
at the Large Hadron Collider at a centre-of-mass energy of 13 TeV, corresponding to an integrated
luminosity of 36.1 fb−1. No significant excess is observed over the Standard Model predictions and
limits are set on the production cross section times branching ratio of a heavy vector particle
produced either in quark–antiquark fusion or through vector-boson fusion. Constraints are also
obtained on the mass and couplings of a singly charged Higgs
boson, in the Georgi–Machacek model, produced through vector-boson fusion.
