Abstract:
A search for neutral heavy resonances is performed in the WW → eν µν decay channel using pp
collision data corresponding to an integrated luminosity of 36.1 fb−1, collected at a centre-
of-mass energy of 13 TeV 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 σX × B(X → WW ) as a function of the resonance mass are
obtained in the mass range between 200 GeV and up to 5 TeV 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.
