New Prospects for Transverse Physics with the PHENIX detector

PHENIX has made measurements of the transverse single spin asymmetry $A_N$ for pi-zero and non-identified charged hadrons near $x_F~\sim~0$ at collider energies, and measurements of pi-zero $A_N$ and pi+/pi- have also been made at the same $\sqrt{s}$ but at $x_F$ up to 0.6 by the STAR and Brahms collaborations. Asymmetries as large as $\sim~30\%$ have been found. Currently, these large asymmetries are thought to come either from higher-twist contributions, modifications to the parton distribution functions (Sivers), modifications to the fragmentation functions (Collins), or even perhaps some combination of the three. Future progress will require separating these effects. We discuss future prospects with the PHENIX detector for reducing these ambiguities in inclusive single spin asymmetries by looking at correlations between hadrons from the same and from back to back jets.
