Description
The SpinQuest experiment (E1039) at Fermilab will measure the azimuthal asymmetry of dimuon pair production via scattering of unpolarized protons from transversely polarized $NH_3$ and $ND_3$ targets. The asymmetry will be measured for both Drell-Yan scattering and $J/\psi$ production. By measuring the asymmetry for the Drell-Yan process, it is possible to extract the Sivers Function for the light anti-quarks in the nucleon. A non-zero asymmetry would be “smoking gun” evidence for a non-zero orbital angular momentum of the light sea-quarks: a possible contributor to the proton’s spin. An overview of the experiment will be presented, as well as details on the SpinQuest polarized target built at the University of Virginia.
