Description
I will discuss the sensitivity to the Higgs self-coupling through $W$ boson fusion di-Higgs production at $e^-e^+$ collider at $\sqrt{s}=3$ TeV (arXiv:2608.05096). The interplay between the Higgs self-coupling modifier ($\kappa_{\lambda}$) and Higgs-gauge boson coupling modifiers ($\kappa_{V}$ and $\kappa_{2V}$) within the $\kappa$ framework, will be discussed. The separation between signal and background will be carried by graph neural network (GNN) based classifier that achieves a signal significance of $\mathscr{Z}\approx 20~\sigma$ at $5~\mathrm{ab}^{-1}$.
