我们将前向碰撞中单自旋不对称性的理论结果（包括胶子饱和效应）与 PHENIX 和 STAR 合作在相对论重离子对撞机上的最新初步实验数据进行对比。虽然我们发现与 STAR 数据总体上合理一致，但我们的结果表明，PHENIX 合作组织观察到的不对称性的强核抑制无法在目前对此问题的理解范围内进行解释。
We confront the theoretical result of single spin asymmetryin forwardcollisionsincluding the gluon saturation effect with the recent preliminary experimental data from the PHENIX and STAR Collaborations at the Relativistic Heavy Ion Collider. While we find overall reasonable agreement with the STAR data, our results indicate that the strong nuclear suppression of the asymmetryobserved by the PHENIX Collaboration cannot be explained within the present understanding of this problem.
