Forward-rapidity $\pi^{0}$-Charged Particle Correlations at STAR from $p^{\uparrow}+p$ Collisions at $\sqrt{s}=200$ GeV

Abstract

RHIC experiments have observed large transverse single-spin asymmetries, $A_{N}$, in inclusive hadron production at forward rapidity. Extending the analysis beyond inclusive measurements, for example, correlations between produced hadrons at forward rapidities, provides the opportunity to decipher between dynamical contributions to $A_{N}$, such as the Collins and Sivers mechanisms. Recent analysis at STAR investigates high pseudorapidity $\pi^{0}$-charged particle correlations from $\sqrt{s}=200$ GeV polarized proton collisions. The $\pi^{0}$'s are detected at $2.5<\eta<4$ with the Forward Meson Spectrometer, and the charged particles are detected in the same pseudorapidity region with the Forward Time Projection Chamber. The status of the analysis will be discussed.
