Description
In this talk I will review the existing proposal of
energy-frontier deep-inelastic scattering at CERN, the Large
Hadron-electron Collider LHeC. I will present the proposal, consisting
in colliding 60 GeV electrons from an energy recovery linac with the LHC
beams or, in the further future, with the HE-LHC or FCC proton and
nuclear beams. Then I will discuss the physics case, focusing on the
possibilities for QCD: parton densities in proton and nuclei, imaging of
hadrons an nuclei through diffraction, investigations of the non-linear
saturation regime, and studies of nuclear modifications of parton
branching and hadronisation. I will emphasise those aspects of these
studies of relevance for the understanding of the initial stages of
high-energy heavy-ion collisions.
