Davoudiasl, Hooman;

A future $e^{+} e^{-}$ circular collider (FCC-ee) may provide a unique probe of the electron Yukawa coupling through Higgs boson production on resonance. Motivated by this exciting possibility, we examine a simple model which can result in $O (10)$ modifications of the Higgs coupling to electrons. The model can also lead to deviations in the electron anomalous magnetic moment, $g_{e} - 2$ , which at present shows a $+ 2.2 σ$ or $- 3.7 σ$ deviation, implied by differing precision determinations of the electromagnetic fine structure constant. The electron $g_{e} - 2$ can be a forerunner for FCC-ee discoveries which, as we elucidate, may not be accessible to the high-luminosity LHC measurements. A simple extension of our model can also account for the current deviation in the muon $g_{μ} - 2$ .
