abstract = {A search for CP violation in the decay kinematics and vector-boson fusion
production of the Higgs boson is performed in the H ! ZZ  ! 4` (` = e, μ) decay channel.
The results are based on proton-proton collision data produced at the LHC at a centre-of-mass
energy of 13TeV and recorded by the ATLAS detector from 2015 to 2018, corresponding
to an integrated luminosity of 139 fb−1. Matrix element-based optimal observables are used
to constrain CP-odd couplings beyond the Standard Model in the framework of Standard
Model effective field theory expressed in the Warsaw and Higgs bases. Differential fiducial
cross-section measurements of the optimal observables are also performed, and a new fiducial
cross-section measurement for vector-boson-fusion production is provided. All measurements
are in agreement with the Standard Model prediction of a CP-even Higgs boson.},
