Description
We investigate the sensitivity to the Higgs trilinear coupling (κ_λ) through di-Higgs production via vector-boson fusion (VBF) at a multi-TeV muon collider. A primary advantage of the muon collider environment is the significantly suppressed QCD background compared to hadron colliders, which provides a remarkably clean experimental signature for probing electroweak processes. We perform a detailed analysis using a dedicated simulation chain, examining the variations in both the production rate and kinematic distributions as a function of κ_λ. We employ advanced machine learning techniques to optimize signal-background separation and enhance the sensitivity to the Higgs potential. We estimate the expected precision on κ_λ. Our results highlight the unique potential of high-energy muon colliders for precision Higgs measurements in the VBF sector.
