Description
Very little is known about nuclear gluon densities.
We explore the direct measurements of nuclear gluon densities via open charm and beauty production at an Electron-Ion Collider (EIC).
In the high-x ranges x ~ 0.05-0.15 (antishadowing) and x>0.3 (EMC effect) strong modifications are expected relative to the incoherent sum the nucleon gluon
distribution.
These effects offer insight into non-nucleonic degrees of freedom and the QCD structure of nucleon-nucleon interactions. We describe the charm production rates in nuclear deep-inelastic scattering (DIS) at large x_B, and comment on methods for charm reconstruction using next-generation detectors at the EIC (pi/K identification, tracking, vertex detection).
