Measurement of Double Helicity Asymmetry in Multi-Particle Production with Polarized Proton-Proton Collision at PHENIX

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/179931A 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").4 pages, 2 figures, to be published in the Proceedings of the 17th International Spin Physics SymposiumNuclear ExperimentMeasurement of Double Helicity Asymmetry in Multi-Particle Production with Polarized Proton-Proton Collision at PHENIXtext
