All figures including auxiliary figures are available at https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/HIGG-2018-30/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 13 TeV 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.JHEP05(2024)105both the Higgs and Warsaw bases using the SMEFT. They are dominated by the interference term between the SM and BSM contributions linear in the Wilson coefficients, O (Λ−2) in the cross-section, with only a small sensitivity to the pure BSM contributions quadratic in the Wilson coefficients, O (Λ−4). This qualitatively implies a low expected sensitivity to missing dimension-eight contributions that also enter at O (Λ−4) in the cross-section, and it is therefore an improvement on analyses relying on rates rather than shapes. Measurements of fiducial differential cross-sections of the optimal-observable distributions are also presented, completing the set of fiducial differential cross-section measurements in the Higgs boson to four-lepton channel. In addition, fiducial cross-sections for VBF production are measured for a VBF-enriched fiducial region for two scenarios: with and without the explicit subtraction of the ggF background. All measurements are consistent with the SM expectation of a CP-even Higgs boson. No significant CP-odd component is observed. The data for all tables and the figures with differential distributions can be viewed at HEPData.
