Measurement of Angular Distributions of Drell-Yan Dimuons in p + d Interaction at 800 GeV/c

Abstract

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 polar angle $\theta$ and azimuthal angle $\varphi$ have been measured over the kinematic range $4.5<m_{\mu \mu }<15$ GeV/c${}^2$, $0<p_T<4$ GeV/c, and $0<x_F<0.8$. No significant cos$2\varphi$ dependence is found in these proton-induced Drell-Yan data, in contrast to the situation for pion-induced Drell-Yan. The data are compared with expectations from models which attribute the cos$2\varphi$ distribution to a QCD vacuum effect or to the presence of the transverse-momentum-dependent Boer-Mulders structure function $h_1^{\perp }$. Constraints on the magnitude of the sea-quark $h_1^{\perp }$ structure functions are obtained.
