Description
Recent studies of high-energy inclusive Higgs boson hadroproduction rates, incorporating fixed-order N$^3$LO QCD corrections, have demonstrated that high-energy resummation effects can contribute up to 10\% at the nominal energies of the FCC. This finding underscores the importance of resummation physics for electroweak processes at 100 TeV. We present new predictions for rapidity and transverse-momentum distributions that probe the emission of a Higgs boson in association with a jet in proton collisions. These results are computed at NLO accuracy in QCD and matched to next-to-leading logarithmic accuracy and beyond (NLL/NLO$^+$) in the high-energy regime. Additionally, we report preliminary progress in extending this approach to $Z$-boson production. To our knowledge, this work represents the first implementation of a matching procedure in the high-energy resummation framework for two-particle final states separated in rapidity. We emphasize that refining fixed-order predictions for Higgs- and Z-boson plus jet distributions is essential for accurately describing key observables in Higgs and electroweak physics at both LHC and FCC energies.
