  • We report a measurement of the angular distributions of Drell-Yan dimuons produced using an 800 GeV/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<m{sub {mu}}{sub {mu}}<15 GeV/c{sup 2}, 0<p{sub T}<4 GeV/c, and 0<x{sub F}<0.8. No significant cos2{phi} 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 cos2{phi} distribution to a QCD vacuum effect or to the presence of the transverse-momentum-dependent Boer-Mulders structure function h{sub 1}{sup perpendicular}.more » Constraints on the magnitude of the sea-quark h{sub 1}{sup perpendicular} structure functions are obtained.« less

  • We report a measurement of the angular distributions of Drell-Yan dimuons produced using an 800 GeV/c proton beam on a hydrogen target. The polar and azimuthal angular distribution parameters have been extracted over the kinematic range 4.5 < m{sub {mu}{mu}} < 15 GeV/c{sup 2} (excluding the {Upsilon} resonance region), 0 < p{sub T} < 4 GeV/c, and 0 < x{sub F} < 0.8. The p+p angular distributions are similar to those of p+d, and both data sets are compared with models which attribute the cos2{phi} distribution either to the presence of the transverse-momentum-dependent Boer-Mulders structure function h{sub 1}{sup {perpendicular}} ormore » to QCD effects. The data indicate the need to include QCD effects before reliable information on the Boer-Mulders function can be extracted. The validity of the Lam-Tung relation in p+p Drell-Yan data is also tested.« less
