Title: Single spin asymmetry in forward pA collisions

Abstract

In this paper, we compute the transverse single spin asymmetry in light hadron production p↑p→hX and p↑A→hX including the gluon saturation effect in the unpolarized nucleon/nucleus. In the forward (large-xF) region, the dominant contribution comes from the so-called derivative term associated with the soft gluonic pole. This leads to the cancellation of nuclear effects in AN which can be tested at the RHIC. We also show that the soft fermionic pole disappears in the saturation environment.

Twist-3 quark-gluon correlation contribution to single-transverse spin asymmetry for direct-photon and single-jet productions in pp collision

Journal Article Kanazawa, K. ; Koike, Y. - Physics of Particles and Nuclei

We study the contribution of the collinear twist-3 quark-gluon correlation to the single transversespin asymmetry in direct-photon and single-jet productions in pp collision. At typical RHIC kinematics we find sizable asymmetries in the forward region of the polarized nucleon while they are almost zero in the backward region. We also find the soft-fermion pole contribution is vanishingly small, suggesting the measurement of these asymmetries provides us with an unique opportunity to determine the net soft-gluon pole function.

Single spin asymmetry in forward $p A$ collisions: Phenomenology at RHIC

Journal Article Benić, Sanjin ; Hatta, Yoshitaka - Physical Review D

We confront the theoretical result of single spin asymmetry (SSA) A_N in forward pA collisions p↑A → hX including the gluon saturation effect with the recent preliminary experimental data from the PHENIX and STAR collaborations at RHIC. While we find overall reasonable agreement with the STAR data, our results indicate that the strong nuclear suppression of the asymmetry A_N ~ A^–1/3 observed by the PHENIX collaboration cannot be explained within the present understanding of this problem.

Single Spin Transverse Asymmetries of Neutral Pions at Forward Rapidities in {radical}(s) = 62.4 GeV Polarized Proton Collisions in PHENIX

Journal Article Chiu, Mickey - AIP Conference Proceedings

In the RHIC run of 2006, PHENIX recorded data from about 20 nb-1 of transversely polarized p+p collisions at {radical}(s) = 62.4 GeV and polarization of about 50%. Also in this last run PHENIX successfully commissioned a new PbWO4 based electromagnetic calorimeter, the Muon Piston Calorimeter (MPC), covering 2{pi} in azimuth and 3.1 < {eta} < 3.7. The forward coverage allows PHENIX to measure high xF {pi}0 production. We present the current status of the analysis for the single inclusive {pi}0 transverse asymmetry AN at forward rapidities in PHENIX.
