Abstract

Although the proton was discovered about 100 years ago, its spin structure still remains a mystery. Recent studies suggest that the orbital angular momentum of sea quarks could significantly contribute to the proton’s spin. The SeaQuest experiment, which recently completed data collection, probed the unpolarized light quark sea distributions of the proton using the Drell-Yan process. Its successor, the SpinQuest (E1039), will access the ū and d Sivers functions using polarized NH₃ and ND₃ targets. A non-zero Sivers asymmetry, observed in SpinQuest, would be a strong indication of non-zero sea-quark orbital angular momentum. The SpinQuest experiment can also probe the sea quark’s transversity distribution, which is relevant for the determination of proton’s tensor charge. Recent study suggests that sea-quarks might contribute significantly to deuteron’s tensor polarized structure functions. This can be further probed in SpinQuest using tensor polarized ND₃ target. The current status and future plan of the experiment are presented.
