Constraints on Gluon Polarization in the proton from PHENIX Double Helicity Asymmetry Data Original Research Article

We present a simple approach to constrain the gluon polarization in the proton, ΔG, in the gluon momentum fraction range 0.02–0.3 from PHENIX latest results on double helicity asymmetry in π0 production from polarized proton-proton collisions at View the MathML source at mid-rapidity.
