  "abstract": "We study the forward-backward asymmetry in the three-body decay process $H\\to Zγ\\to\\overline{f}fγ$, induced by complex form factors in the $HZγ$ vertex. To estimate its magnitude, we derive constraints on the real and imaginary parts of the $CP$-violating form factor $h_3^{Zγ}$ using current LHC measurements, obtaining upper limits of about $0.9$ GeV. These bounds are of the same order of magnitude as those derived from electric dipole moments (EDM). We find that the asymmetry can reach values of order $10^{-1}$ and may be accessible at the HL-LHC.",
