Description
The Large Hadron-electron Collider and the Future Circular Collider in electron-hadron mode [1] will make possible the study of DIS in the TeV regime providing electron-proton (nucleus) collisions with per nucleon instantaneous luminosities around $10^{34}$ ($10^{33}$) cm$^{-2}$s$^{-1}$. In this talk we review the opportunities for the determination of the nuclear parton structure at small $x$ in view of the recent findings in proton-nucleus collisions at the LHC. We will also discuss the possibilities of establishing the existence of a new non-linear regime of QCD at small $x$ which requires both $ep$ and $eA$ data to be available at TeV scale energies, by examining different observables sensitive to non-linear dynamics that, besides, provide differential information on proton and nuclear structure.
