摘要:

布鲁克海文国家实验室的相对论重离子对撞机上的极化质子束为观察胶子和夸克之间的硬散射提供了一个独特的环境。PHENIX实验记录了$\sqrt(s_{NN})=$ 200 GeV和62.4 GeV的碰撞,产生的数据与深度非弹性散射实验测量的数据是互补的。极化质子-质子碰撞耦合了参与者的色荷,可以直接探测极化胶子和反夸克的分布。PHENIX探测器非常适合测量许多对质子自旋结构敏感的末态粒子。我们将简要概述PHENIX自旋计划,我们将报告的结果,状态和前景的许多探针访问PHENIX实验,将被纳入未来的全球分析世界数据的偏振硬散射。

英文摘要:

The polarized proton beams at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory provide a unique environment to observe hard scattering between gluons and quarks. The PHENIX experiment has recorded collisions at $\sqrt(s_{NN})=$200 GeV and 62.4 GeV to yield data which are complementary to those measured by deep inelastic scattering experiments. Polarized proton-proton collisions can directly probe the polarized gluon and anti-quark distributions as the collisions couple the color charges of the participants. The PHENIX detector is well suited to measure many final-state particles sensitive to the proton's spin structure. We will give a brief overview of the PHENIX Spin Program and we will report results, status and outlook of the many probes accessible to the PHENIX experiment which will be incorporated into future global analyses of world data on polarized hard scattering.
