Higgs self-coupling measurement prospects in the $HH \rightarrow b\bar{b} \ell\ell + E_{\text{T}}^{\text{miss}}$ channel at the FCC-hh

    The Future Circular Collider project aims in its second phase to a proton-proton collider at $\sqrt{s}=100$ TeV (FCC-hh), with the goal to deliver up to 30~$\text{ab}^{-1}$ of integrated luminosity. Such a project has the potential to determine the Higgs-self coupling at few per-cent level, by combining several decay channels and categories.
    This paper presents prospect studies for diHiggs measurements in the $HH \rightarrow b\bar{b} \ell\ell + E_{\text{T}}^{\text{miss}}$ final state,
    thus analyzing a channel with missing transverse energy and therefore sensitive to pile-up. Two different detector scenarios and three different sets of systematic uncertainties were assumed to obtain projected uncertainties on the self-coupling modifier $\kappa_{\lambda}$.
