Effect of polarized gluon distribution on spin asymmetries for neutral and charged pion production
arXiv:hep-ph/0403102 · doi:10.1103/PhysRevD.71.014022
Abstract
A longitudinal double spin asymmetry for π^0 production has been measured by the PHENIX collaboration. The asymmetry is sensitive to the polarized gluon distribution and is indicated to be positive by theoretical predictions. We study a correlation between behavior of the asymmetry and polarized gluon distribution in neutral and charged pion production at RHIC.
