$\sqrt{s} = 200$ GeV上p+p碰撞中自旋相关的正向粒子关联

Spin-dependent Forward Particle Correlations in p+p Collisions at $\sqrt{s} = 200$ GeV

Nikola Poljak

摘要:

STAR合作报告了在$\sqrt{s} = 200$ GeV的极化质子碰撞中产生$π^0$介子的横向单自旋不对称性的精确测量。这些测量值是使用模块化前向探测器获得的。覆盖$2.5 < η< 4.0$区域的前向介子谱仪(FMS)及其工程原型提供了更高的接受度,这是自旋相关研究所需要的,可以解开对前向π ^0 $不对称性的贡献。我们报告分析的状态。

英文摘要:

The STAR collaboration has reported precision measurements of the transverse single spin asymmetries for the production of the $π^0$ mesons from polarized proton collisions at $\sqrt{s} = 200$ GeV. These measurements were obtained using modular forward detectors. The Forward Meson Spectrometer (FMS), covering a region of $2.5 < η< 4.0$, and its engineering prototype, provide increased acceptance, as needed for spin-dependent correlation studies that could disentangle contributions to the forward \$pi^0$ asymmetries. We report on the status of the analysis.
