Description
Pioneering measurements of Single-Spin Asymmetries (SSAs) at HERMES and COMPASS, followed by high-precision studies at JLab, have been essential for uncovering the rich and extraordinary variety of non-perturbative effects in hadronic structure. Semi-inclusive and exclusive hadron production—both single and dihadron, in current and target fragmentation regions—provides a wide range of spin- and azimuthal-angle–dependent observables, offering unique sensitivity to the dynamics of quark–gluon interactions. Investigations of spin-dependent structure functions and the underlying transverse momentum distributions of partons are now driving upgrades of existing facilities and shaping the design of new ones worldwide.
This talk will highlight the impact of SSA measurements and explore future directions in studies of the 3D hadron structure through electroproduction,
