Description
The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. An ERL will provide electrons to collide with the HL-LHC, HE-LHC and the FCC-hh proton beams to achieve centre-of-mass energies 1.3-3.5 TeV and luminosities $\sim 10^{34}$ cm$^{-2}$s$^{-1}$. These three configurations will extend the kinematic plane by more than one order of magnitude towards smaller $x$ and larger $Q^2$ than HERA. DIS measurements in such machines offer unprecedented possibilities to enlarge our knowledge on parton densities through a complete unfolding of all flavours in a single experimental setup to be compared with data from hadron colliders as an independent input and as a test of factorisation, and to determine $\alpha_s$. In this talk we review the most recent developments on these subjects.
