Query: Constraining the nuclear gluon distribution in $eA$ processes at RHIC   A systematic determination of the gluon distribution is of fundamental
interest in understanding the parton structure of nuclei and the QCD dynamics.
Currently, the behavior of this distribution at small $x$ (high energy) is
completely undefined. In this paper we analyze the possibility of constraining
the nuclear effects present in $xg^A$ using the inclusive observables which
would be measured in the future electron-nucleus collider at RHIC. We
demonstrate that the study of nuclear longitudinal and charm structure
functions allows to estimate the magnitude of shadowing and antishadowing
effects in the nuclear gluon distribution.
