Abstract

We report a measurement of the angular distributions of Drell-Yan dimuons produced using an 800GeV/c proton beam on a deuterium target. The muon angular distributions in the dilepton rest frame have been measured over the kinematic range 4.5<mμμ<15GeV/c2, 0<pT<4GeV/c, and 0<xF<0.8. No significant cos 2 dependence is found in these proton-induced Drell-Yan data, in contrast with the situation for pion-induced Drell-Yan data. The data are compared with expectations from models which attribute the cos 2 distribution to a QCD vacuum effect or to the presence of the transverse-momentum-dependent Boer-Mulders structure function h1 . Constraints on the magnitude of the sea-quark h1 structure functions are obtained.
