Description
The nucleon spin structure has been understood by nucleon TMDs and GPDs. Conventionally, TMDs and GPDs are obtained from, for example, the SIDIS and DVCS processes utilizing lepton beams. A complementary approach is the measurement of (un)polarized Drell-Yan processes with hadron beams. The universality properties of nucleon TMDs and GPDs determined in space-like and time-like experimental approaches could be checked.
In this talk, we will discuss the recent results of nucleon Sivers, transversality, and Boer-Mulders TSAs measured by the COMPASS experiment, and sketch the plan for measuring nucleon GPDs by the exclusive pion-induced Drell-Yan process at J-PARC.
