Helicity Parton Distributions at a Future Electron-Ion Collider: A Quantitative Appraisal
arXiv:1206.6014 · doi:10.1103/PhysRevD.86.054020
Abstract
We present a quantitative assessment of the impact a future electron-ion collider will have on determinations of helicity quark and gluon densities and their contributions to the proton spin. Our results are obtained by performing a series of global QCD analyses at next-to-leading order accuracy based on realistic sets of pseudo-data for the inclusive and semi-inclusive deep-inelastic scattering of longitudinally polarized electrons and protons at different, conceivable center-of-mass system energies.
