Description
The FCC-hh, colliding protons at a centre-of-mass energy of 84 TeV, will produce single and double Higgs boson samples orders of magnitude larger than those available at the LHC. This unprecedented statistics will enable few-percent precision on rare decays such as H→μμ, H→γγ, and H→Zγ, a stringent test of the top Yukawa coupling through ttH production, and a direct measurement of the Higgs self-coupling down to the percent level. Triple Higgs production could also come within reach, with recent studies offering a first handle on the quartic Higgs self-coupling alongside the trilinear one. We review these projected measurements, highlighting how they complement FCC-ee's precision electroweak program and push the Higgs sector to an unprecedented level of scrutiny.
