Semi-inclusive Deep-Inelastic Scattering, Parton Distributions and Fragmentation Functions at a Future Electron-Ion Collider

Understand

We present a quantitative assessment of the impact a future Electron-Ion Collider would have in the determination of parton distribution functions in the proton and parton-to-hadron fragmentation functions through semi-inclusive deep-inelastic electron-proton scattering data.

• Specifically, we estimate the kinematic configurations for which the forthcoming data are expected to have the most significant impact in the precision of these distributions, computing the respective correlation and sensitivity coefficients.
• Implementing the reweighting technique over sets of simulated data with realistic uncertainties for two different center-of-mass energies, we analyse the resulting upgraded sets of PDFs and FFs, which have significantly reduced uncertainties.
