Abstract

The Future Circular Collider project aims in its second phase to a proton-proton collider at √(s)=100 TeV (FCC-hh), with the goal to deliver up to 30~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 → bb ℓℓ + E_T^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 κ_λ.
