GeV = 200时RHIC极化pp碰撞中π +,π-和η产生的PHENIX最近结果

Recent PHENIX Results on pi+, pi-, and eta Production in polarized pp Collisions at RHIC at sqrt(s) = 200 GeV

摘要:

极化质子-质子碰撞中强子产生的双螺旋不对称性的测量对自旋相关的部分子分布函数,特别是胶子分布函数敏感。本研究的重点是双螺旋度不对称的η和带电π介子生产在中等快度,以及η截面和碎裂功能。

英文摘要:

Measurements of double helicity asymmetries for inclusive hadron production in polarized proton-proton collisions are sensitive to spin-dependent parton distribution functions, in particular to the gluon distribution function. This study focuses on double helicity asymmetries in eta and charged pion production at mid-rapidity, as well as on the eta cross section and fragmentation functions.
