TMDs and Drell-Yan Experiments at Fermilab and J-PARC
The roles of the Drell-Yan experiments in studying the
Transverse-Momentum-Dependent (TMD) parton distributions are discussed. Recent
results from the Fermilab E866 experiment on the angular distributions of
Drell-Yan dimuons in and at 800 GeV/c are presented. These data are
compared with the pion-induced Drell-Yan data, and with models which attribute
the azimuthal distribution to the presence of the
transverse-momentum-dependent Boer-Mulders structure function .
Constraints on the magnitude of the sea-quark structure functions
are obtained. Future prospects for studying the TMDs with Drell-Yan experiments
at Fermilab and J-PARC are also discussed.Comment: 10 pages, 3 figures, to appear in the Proceedings of "Transversity

Partonic substructure of nucleons and nuclei with dimuon production
Dimuon production has been studied in a series of fixed-target experiments at
Fermilab during the last two decades. Highlights from these experiments,
together with recent results from the Fermilab E866 experiment, are presented.
Future prospects for studying the parton distributions in the nucleons and
nuclei using dimuon production are also discussed.Comment: 6 pages. Contribution to the proceedings of "Achievements and New
Directions in subatomic Physics: Workshop in Honour of Tony Thomas' 60th
Birthday," Adelaide, South Australia, February 15-19, 2010
