Abstract:
We present a quantitative assessment of the impact of a future EIC on determinations of helicity quark and gluon densities and their contributions to the proton spin. Our results are obtained by performing global QCD analyses at NLO accuracy based on realistic sets of pseudo-data for various conceivable center-of-mass system energies.
