Title: Comparison of transverse single-spin asymmetries for forward π⁰ production in polarized pp, pAl and pAu collisions at nucleon pair c.m. energy √sNN=200 GeV

Abstract

The STAR collaboration reports a measurement of the transverse single-spin asymmetries, $A_{N}$ , for neutral pions produced in polarized proton collisions with protons ( $p p$ ), with aluminum nuclei ( $p Al$ ) and with gold nuclei ( $p Au$ ) at a nucleon-nucleon center-of-mass energy of 200 GeV. Neutral pions are observed in the forward direction relative to the transversely polarized proton beam, in the pseudorapidity region $2.7 < η < 3.8$ . Results are presented for $π^{0} s$ observed in the STAR forward meson spectrometer electromagnetic calorimeter in narrow Feynman x ( $x_{F}$ ) and transverse momentum ( $p_{T}$ ) bins, spanning the range $0.17 < x_{F} < 0.81$ and $1.7 < p_{T} < 6.0 GeV / c$ . For fixed $x_{F} < 0.47$ , the asymmetries are found to rise with increasing transverse momentum. For larger $x_{F}$ , the asymmetry flattens or falls as $p_{T}$ increases. Parametrizing the ratio $r (A) \equiv A_{N} (p A) / A_{N} (p p) = A^{P}$ over the kinematic range, the ratio $r (A)$ is found to depend only weakly on $A$ , with $(P) = - 0.027 \pm 0.005$ . No significant difference in $P$ is observed between the low- $p_{T}$ region, $p_{T} < 2.5 GeV / c$ , where gluon saturation effects may play a role, and the high- $p_{T}$ region, $p_{T} > 2.5 GeV / c$ . It is further observed that the value of $A_{N}$ is significantly larger for events with a large- $p_{T}$ isolated $π^{0}$ than for events with a nonisolated $π^{0}$ accompanied by additional jetlike fragments. The nuclear dependence $r (A)$ is similar for isolated and nonisolated $π^{0}$ events.

  abstractNote = {The STAR collaboration reports a measurement of the transverse single-spin asymmetries, AN, for neutral pions produced in polarized proton collisions with protons (pp), with aluminum nuclei (pAl) and with gold nuclei (pAu) at a nucleon-nucleon center-of-mass energy of 200 GeV. Neutral pions are observed in the forward direction relative to the transversely polarized proton beam, in the pseudorapidity region 2.7<η<3.8. Results are presented for π0s observed in the STAR forward meson spectrometer electromagnetic calorimeter in narrow Feynman x (xF) and transverse momentum (pT) bins, spanning the range 0.17<xF<0.81 and 1.7<pT<6.0 GeV/c. For fixed xF<0.47, the asymmetries are found to rise with increasing transverse momentum. For larger xF, the asymmetry flattens or falls as pT increases. Parametrizing the ratio r(A)≡AN(pA)/AN(pp)=AP over the kinematic range, the ratio r(A) is found to depend only weakly on A, with (P)=-0.027±0.005. No significant difference in P is observed between the low-pT region, pT<2.5 GeV/c, where gluon saturation effects may play a role, and the high-pT region, pT>2.5 GeV/c. It is further observed that the value of AN is significantly larger for events with a large-pT isolated π0 than for events with a nonisolated π0 accompanied by additional jetlike fragments. The nuclear dependence r(A) is similar for isolated and nonisolated π0 events.},
