New Insight of the Drell-Yan Angular Distributions

Abstract:

High precision data of dilepton angular distributions in Drell-Yan andZ-boson production have revealed a large violation of the Lam-Tung relation.Using an intuitive approach we show that the violation of the Lam-Tungrelation, as well as the kinematic dependencies of the angular distributionscoefficents, can be well understood. Implication of this work on other hardprocesses and on the extraction of the Boer-Mulders function will also bediscussed.
