Abstract

The lepton angular distribution coefficients Ai for Z boson production in pp and p¯p collisions have been measured at the LHC and the Tevatron. A recent study showed that many features of the measured angular distribution coefficients, including the transverse momentum (qT) and rapidity dependencies and the violation of the Lam-Tung relation, can be well described using an intuitive geometric approach. In this paper, we extend this geometric approach to describe the angular distribution coefficients for W boson produced in p¯p collisions at the Tevatron. We first compare the data with a perturbative QCD calculation at O(αs2). We then show that the data and QCD calculations can be well described with the geometric approach. Implications for future studies at the LHC energy are also discussed.
