Z boson transverse momentum spectrum from the lepton angular distributions
arXiv:1002.1850 · doi:10.1007/JHEP11(2010)153
Abstract
In view of recent discussions concerning the possibly limiting energy resolution systematics on the measurement of the Z boson transverse momentum distribution at hadron colliders, we propose a novel measurement method based on the angular distributions of the decay leptons. We also introduce a phenomenological parametrization of the transverse momentum distribution that adapts well to all currently available predictions, a useful tool to quantify their differences.
