Non-global logarithms and fiducial transverse-momentum-dependent observables in deep-inelastic scattering

Extracting the intrinsic transverse-momentum structure of quarks from deep-inelastic scattering data requires separating nonperturbative effects from perturbative radiation, which broadens the measured transverse-momentum distributions. We address this problem in electron--proton scattering, $ep\to eX$, by introducing...
