Study of the $\cal{CP}$ properties of the top quark Yukawa interaction in $t\bar{t}H$ and $tH$ events with $H\to~\gamma\gamma$
These procedings present the first search for $\cal{CP}$-violation in the top Yukawa coupling using $t\bar{t}H$ and $tH$ production modes in the diphoton decay channel ($H\to\gamma\gamma$). The analysis is based on the 139~fb$^{-1}$ of proton-proton collision data at center-of-mass energy $\sqrt{s}$...
