Description
Recent studies of inclusive Higgs production at N$^3$LO have shown that high-energy resummation effects can reach the 10% level at future hadron colliders, indicating that precision Higgs and electroweak physics is increasingly sensitive to QCD dynamics beyond fixed order. Motivated by this observation, we present recent developments of the JETHAD-DYnamis framework, a high-energy resummation platform for the study of Higgs- and electroweak-boson production in association with jets from HL-LHC to FCC energies. The framework combines NLO fixed-order calculations with next-to-leading energy-logarithmic resummation and is being extended to include realistic final-state descriptions through matching with Monte Carlo event generators. We discuss recent progress in the treatment of rapidity-separated Higgs- and $Z/\gamma^*$-boson plus jet final states, including angular correlations, polarization effects, and lepton-level observables. Particular emphasis is placed on precision observables sensitive to high-energy dynamics and on their role in future measurements of the Higgs and electroweak sectors.
These developments represent a step toward a unified high-energy framework for precision collider phenomenology, providing new opportunities for the interpretation of measurements at the HL-LHC and for physics studies at future hadron colliders.
