Sivers functions: a status report
ORAL · Invited
Abstract
Exploring transverse momentum dependent parton distribution functions (TMD PDFs) has been one of the major research topics in hadron physics in recent years. TMD PDFs provide three-dimensional (3D) imaging of the nucleon in both the longitudinal and transverse momentum space. Sivers function is one of the most studied TMD PDFs in the community. It describes the distribution of unpolarized partons inside a transversely polarized nucleon, through a correlation between the transverse spin of the nucleon and the transverse momentum of the parton with respect to the nucleon's moving direction. In this talk, we will provide the latest development in the field in the global anaysis of the Sivers function from various processes, as well as the predictions for the polarized Drell-Yan process at the Fermilab.
