Description
We present a comprehensive study of the angular coefficients of Z and W boson production at hadron colliders across a range of kinematic regimes. Predictions are obtained by consistently matching transverse-momentum resummation at next-to-next-to-leading logarithmic accuracy in the small-qT region onto next-to-leading order fixed-order QCD, valid at large qT, and are compared with ATLAS, CMS and LHCb measurements at the LHC and CDF data at the Tevatron. Resummation effects are found to be concentrated in the intermediate region qT ~ 20-50 GeV, where they moderately and systematically improve the description of several coefficients, without degrading agreement elsewhere.
