Description
The Higgs boson self-coupling is accessible in the double Higgstrahlung process $e^+e^- \rightarrow ZHH$ and the double $WW$ fusion process $e^+e^- \rightarrow \nu \bar{\nu}HH$. Present ILC studies typically evaluate sensitivity to this coupling at center-of-mass energies of $\sqrt{s}=500$ GeV and $\sqrt{s}=1000$ GeV, two well-established ILC operating points. In this study we investigate the ILC sensitivity to the self-coupling at $\sqrt{s}$ from turnon threshold to above 1000 GeV.
