This article presents the results of two studies of Higgs boson properties using the WW∗(→eνμν)jjWW∗(→eνμν)jj final state, based on a dataset corresponding to 36.1fb−136.1fb−1 of s=13s ​=13 TeV proton–proton collisions recorded by the ATLAS experiment at the Large Hadron Collider. The first study targets Higgs boson production via gluon–gluon fusion and constrains the CP properties of the effective Higgs–gluon interaction. Using angular distributions and the overall rate, a value of tan⁡(α)=0.0±0.4(stat.)±0.3(syst.)tan(α)=0.0±0.4(stat.)±0.3(syst.) is obtained for the tangent of the mixing angle for CP-even and CP-odd contributions. The second study exploits the vector-boson fusion production mechanism to probe the Higgs boson couplings to longitudinally and transversely polarised W and Z bosons in both the production and the decay of the Higgs boson, these couplings have not been directly constrained previously.
