This paper presents for the first time a precise measurement of the production properties of the Z boson in the full phase space of the decay leptons. This is in contrast to the many previous precise unfolded measurements performed in the fiducial phase space of the decay leptons. The measurement is obtained from proton–proton collision data collected by the ATLAS experiment in 2012 at √s = 8TeV at the LHC and corresponding to an integrated luminosity of 20.2 fb−1. The results, based on a total of 15.3 million Zbosondecaystoelectronandmuonpairs,extendandimprove a previous measurement of the full set of angular coefficients describing Z-boson decay. The double-differential crosssection distributions in Z-boson transverse momentum pT and rapidity y are measured in the pole region, defined as 80 < m <100GeV,over the range |y| < 3.6.
