Spin-dependent Forward Particle Correlations in p+p Collisions at $\sqrt{s} = 200$ GeV

Abstract

The STAR collaboration has reported precision measurements of the transverse single spin asymmetries for the production of the $\pi^0$ mesons from polarized proton collisions at $\sqrt{s} = 200$ GeV. These measurements were obtained using modular forward detectors. The Forward Meson Spectrometer (FMS), covering a region of $2.5 < \eta < 4.0$, and its engineering prototype, provide increased acceptance, as needed for spin-dependent correlation studies that could disentangle contributions to the forward \$pi^0$ asymmetries. We report on the status of the analysis.
