Description
Higgs boson production in association with jets is a key process for precision tests of the Standard Model, particularly in the phase-space region selected by Vector Boson Fusion-type cuts, where large hierarchies between invariant masses and transverse momenta arise.
In this kinematic regime, fixed-order perturbative predictions become insufficient and all-order resummation of high-energy logarithms is required.
We investigate Higgs plus jets production within the High Energy Jets (HEJ) framework, which provides a systematic resummation of such logarithmic contributions.
We present novel results for Higgs production in association with a quark-antiquark pair. This process constitutes a relevant background to di-Higgs searches, and its accurate theoretical description is essential to reduce uncertainties in Higgs-sector measurements at the High-Luminosity LHC.
Finally, we assess the impact of the resummation of Higgs plus quark-antiquark production -- relevant at next-to-leading logarithmic accuracy -- on Higgs plus jets observables. (12' presentation + 3' discussion)
