Precise predictions for joint polarization fractions in W Z production at the LHC
Abstract
We achieve for the first time NNLO QCD + NLO EW accuracy for doubly polarized W Z inclusive production at the LHC, in the case of fully leptonic decays. Additionally, we provide estimates for missing higher-order uncertainties in QCD associated with doubly polarized differential cross sections and joint polarization fractions, obtained both with standard scale variations and with a theory-nuisance-parameter approach. The study is carried out in the fiducial setup of a recent ATLAS analysis of Run-2 data.
