Test of $CP$ Invariance in Higgs Boson Vector-Boson-Fusion Production Using the $H\to {\hat{I}}^3{\hat{I}}^3$ Channel with the ATLAS Detector

ATLAS Collaboration

A test of $CP$ invariance in Higgs boson production via vector-boson fusion has been performed in the $H\to {\hat{I}}^3{\hat{I}}^3$ channel using 139 fb${}^{-1}$ of proton-proton collision data…
