Drell-Yan process and nucleon spin

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The role of the Drell-Yan process in studying nucleon spin is discussed. Recent results from the Fermilab E866 experiment on the angular distributions of Drell-Yan dimuons in p+p and p + d at 800 GeV/c are presented. These data are compared with the pion-induced Drell-Yan data, and with models which attribute the cos 2φ azimuthal distribution to the presence of the transversemomentum-dependent Boer-Mulders structure function h1. Constraints on the magnitude of the sea-quark h1 structure functions are obtained. Future prospects for studying the TMDs with Drell-Yan experiments at Fermilab and J-PARC are also discussed.
