Abstract: The FCC-hh is a proposed circular hadron collider at an energy of 100 TeV. The total integrated luminosity is expected to be around 30 ab−1. With such a large dataset, 400 times more double-Higgs events are expected than with the full HL-LHC dataset, allowing to measure the Higgs self-coupling with high precision. As a consequence, also rarer final states, which are not within reach of the (HL)-LHC, have good prospects at the FCC-hh. One such final state is the $bbZZ(llνν)$ channel, which has only an Branching Ratio of 0.12\%. With a regular cut-based analysis the potential of this channel is very limited.This study implements a multivariate analysis using neural networks to see if it is a feasible channel that can be used to help to improve the Higgs self-coupling measurement.Upper limits on the di-Higgs production cross-section are derived in order to assess the potential of this channel.
