Description

We study the prospects for measuring nuclear modifications of the gluon density (gluonic EMC effect, antishadowing, shadowing) using open heavy flavor production (charm, beauty) at a future Electron-Ion Collider (EIC). Such direct measurements complement indirect studies of nuclear gluons through DGLAP evolution and could substantially advance our understanding of QCD in nuclei. Building on the experience with HERA, we discuss (a) the expected heavy quark production rates on nuclei at EIC; (b) the possible methods of charm/beauty reconstruction at EIC and their requirements; (c) prospects of open charm/beauty measurements at x > 0.1; (d) specifics of nuclear ratio measurements of heavy meson production. We report about results from an on-going R&D project dedicated to heavy flavor production at EIC (process simulations, physics impact).
