Measurement of Double Helicity Asymmetry in Multi-Particle Production with Polarized Proton-Proton Collision at PHENIX
arXiv:0706.1064 · doi:10.1063/1.2750799
Abstract
A goal of the PHENIX experiment is to obtain the polarized gluon distribution function in the proton. Double helicity asymmetry in multi-particle production with polarized proton-proton collision is measured at midrapidity with RHIC Run 2005 data. This result excludes the maximum positive gluon polarization ("GRSV-max").
