description: The first measurement of lepton-jet momentum imbalance and azimuthal correlation in lepton-proton scattering at high momentum transfer is presented. These data, taken with the H1 de-tector at HERA, are corrected for detector effects using an unbinned machine learning algorithm(OmniFold), which considers eight observables simultaneously in this first application. The un-folded cross sections are compared to calculations performed within the context of collinear ortransverse-momentum-dependent (TMD) factorization in Quantum Chromodynamics (QCD) as wellas Monte Carlo event generators. The measurement probes a wide range of QCD phenomena, in-cluding TMD parton distribution functions and their evolution with energy in so far unexploredkinematic regions.
