### Description

The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. It consists of an ERL providing electrons to collide with the HL-LHC, HE-LHC and the FCC-hh proton beams. These ep configurations will achieve centre-of-mass energies 1.3-3.5 TeV and luminosities $\sim 10^{34}$ cm$^{−2}$ s$^{-1}$ which extends the HERA kinematic coverage by more than one order of magnitude towards smaller $x$ and larger $Q^2$. DIS measurements in such machines will greatly 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. They will also allow a very precise determination of $\alpha_s$. In this talk we review the most recent developments on these subjects.
