We present the first measurement of the electron angular distribution parameter [Formula Presented] in [Formula Presented] events produced in proton-antiproton collisions as a function of the W boson transverse momentum. Our analysis is based on data collected using the DØ detector during the 1994–1995 Fermilab Tevatron run. We compare our results with next-to-leading order perturbative QCD, which predicts an angular distribution of [Formula Presented] where [Formula Presented] is the polar angle of the electron in the Collins-Soper frame. In the presence of QCD corrections, the parameters [Formula Presented] and [Formula Presented] become functions of [Formula Presented] the W boson transverse momentum. This measurement provides a test of next-to-leading order QCD corrections which are a non-negligible contribution to the W boson mass measurement. © 2001 The American Physical Society.
