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 $~10^{34}$ cm$^{-2}$s$^{-1}$. They will
enlarge the kinematic plane by more than one order of magnitude
towards smaller $x$ and larger $Q^2$ than HERA. DIS measurements in
such configurations offer unprecedented possibilities to enlarge our
knowledge on parton densities through a complete unfolding of all
flavours, both in a single experimental setup and combined with data
from hadron colliders where precise factorisation tests can be
performed. In this talk we review the most recent developments on the
determination of proton PDFs and the measurement of $\alpha_s$ at both
the LHeC and the FCC-eh.
