Description
Recent analyses on high-energy inclusive Higgs-boson rates in proton collisions via the gluon fusion channel, matched with the state of-the-art fixed-order N3LO accuracy, have shown that the impact of high-energy resummation corrections reaches 10% at the FCC nominal energies. This supports the statement that electroweak physics at 100 TeV is expected to receive relevant contributions from small-x physics. In this talk we will present novel predictions for transverse-momentum and rapidity distributions sensitive the inclusive emission of a Higgs boson in association with a light-flavored jet in proton collisions, calculated within the NLL accuracy of the energy-logarithmic resummation as implemented in the JETHAD code and matched with NLO fixed-order computations from POWHEG. According to our knowledge, this represent a first and novel implementation of a matching procedure in the context of the high-energy resummation for rapidity-separated two-particle final states. We come out with the message that the improvement of fixed-order calculations on Higgs-plus-jet QCD distributions is a core ingredient to reach the precision level of the description of observables relevant for the Higgs physics at current LHC energies as well as at nominal FCC ones.
