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 $\sigma _X\times B(X \rightarrow WW)$ as a function of the resonance mass are obtained in the mass range between 200 $\,\text {GeV}$ and up to 5 $\,\text {TeV}$ 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.engjournal article2019-02-05
