Determination of $\kappa_\text{t}$ from $\text{t}\bar{\text{t}}$, $\text{t}\bar{\text{t}}\text{t}\bar{\text{t}}$, and others

In this document I report the determination of the Yukawa coupling of the top quark in $\text{t}\bar{\text{t}}$ and $\text{t}\bar{\text{t}}\text{t}\bar{\text{t}}$ final states in ATLAS and CMS. I will also briefly describe the determination of $\kappa_\text{t}$ and its CP structure from $\text{t}\bar{\text{t}}\text{H}$ final states.
