Search for heavy resonances decaying into WW in the eνμν final state in pp collisions at √s=13 TeV with the ATLAS detector

A search for neutral heavy resonances is performed in the WW? e decay channel using pp collision data corresponding to an integrated luminosity of 36.1fb-1, collected at a centre-of-mass energy of 13TeV by the ATLAS detector at the Large Hadron Collider. No evidence of such heavy resonances is found. In the search for production via the quark�antiquark annihilation or gluon�gluon fusion process, upper limits on ? X ? B(X? WW) as a function of the resonance mass are obtained in the mass range between 200GeV and up to 5TeV for various benchmark models: a Higgs-like scalar in different width scenarios, a two-Higgs-doublet model, a heavy vector triplet model, and a warped extra dimensions model. In the vector-boson fusion process, constraints are also obtained on these resonances, as well as on a Higgs boson in the Georgi�Machacek model and a heavy tensor particle coupling only to gauge bosons. � 2018, CERN for the benefit of the ATLAS collaboration.
