Description
After decommissioning in 2016, PHENIX continues releasing new results making significant contribution to our understanding of the nucleon’s spin structure on partonic level and parton dynamics within the polarized nucleon. In this talk we summarize the highlights of the PHENIX spin program from longitudinally and transversely polarized proton-proton collisions as well as from transversely polarized proton collisions with nuclei. We discuss in more detail the most recent results for transverse single spin asymmetry in forward eta-meson production, presented as a function of xF and pT, and compared to pi0-meson asymmetries and Twist-3 calculations (arXiv: 2509.13497).
