dc.description.abstract | Results are presented from data recorded in 2009 by the PHENIX experiment at the Relativistic Heavy Ion Collider for the double-longitudinal spin asymmetry, ALL, for π0 and η production in √s=200??GeV polarized p+p collisions. Comparison of the π0 results with different theory expectations based on fits of other published data showed a preference for small positive values of gluon polarization, ΔG, in the proton in the probed Bjorken x range. The effect of adding the new 2009 π0 data to a recent global analysis of polarized scattering data is also shown, resulting in a best fit value ΔG [0.05,0.2] DSSV=0.06 +0.11 ?0.15 in the range 0.05<x<0.2, with the uncertainty at Δχ2=9 when considering only statistical experimental uncertainties. Shifting the PHENIX data points by their systematic uncertainty leads to a variation of the best-fit value of ΔG [0.05,0.2] DSSV between 0.02 and 0.12, demonstrating the need for full treatment of the experimental systematic uncertainties in future global analyses. | en_US |
