Test of CP Invariance in Higgs Boson Vector-Boson-Fusion Production Using the H RIGHTWARDS ARROW γγ Channel with the ATLAS Detector

Popis výsledku v původním jazyce

A test of CP invariance in Higgs boson production via vector-boson fusion has been performed in theH RIGHTWARDS ARROW γγ channel using 139 fb-1 of proton-proton collision data atffiffiffisp1/4 13 TeV collected by the ATLASdetector at the LHC. The optimal observable method is used to probe the CP structure of interactionsbetween the Higgs boson and electroweak gauge bosons, as described by an effective field theory. No signof CP violation is observed in the data. Constraints are set on the parameters describing the strength of theCP-odd component in the coupling between the Higgs boson and the electroweak gauge bosons in twoeffective field theory bases: ~d in the HISZ basis and cH ~W in the Warsaw basis. The results presented are themost stringent constraints on CP violation in the coupling between Higgs and weak bosons. The 95% C.L.constraint on ~d is derived for the first time and the 95% C.L. constraint on cH ~W has been improved by afactor of 5 compared to the previous measurement.
