“…In the Standard Model, multiple Higgs production at the LHC is rather suppressed [8][9][10][11][12][13][14]. Any precise enough direct measurement of the Higgs-boson trilinear coupling λ SM hhh will hence be challenging [15][16][17], and it will be impossible to get any information on the quartic Higgs selfinteraction λ SM hhhh [18,19].…”

We present a phenomenological study of triple-Higgs production in which we estimate the prospects for measuring the form of the Higgs potential at future circular collider projects. We analyze proton-proton collisions at a center-of-mass energy of 100 TeV and focus on two different signatures in which the final state is made of four b-jets and either a pair of photons or a pair of tau leptons. We study the resulting sensitivity on the Higgs cubic and quartic self-interactions and investigate how it depends on the b-tagging, tau-tagging and photon resolution performances of detectors that could be designed for these future machines. We then discuss possible luminosity goals for future 100 TeV collider projects that would allow for a measurement of the Higgs potential and its possible departures from the Standard Model expectation.
