Description
The Large Hadron electron Collider is a proposed upgrade of the HL-LHC. It will add an energy recovery racetrack to the CERN accelerator complex. The ERL will provide 50 GeV electrons to collide with the LHC beams, resulting in $ep$ ($eA$) collisions with cms energies $\sim 1.2\ (0.75)$ TeV/nucleon and instantaneous luminosities $\sim 10^{34}\ (5\cdot 10^{32}$) cm$^{-2}$s$^{-1}$. It could be built to start operation after the HL-LHC, and deliver integrated ep luminosities around 1 ab$^{-1}$, serving as a bridge between the LHC and the next flagship project at CERN. If the ERL is added to the FCC, FCC-eh, it would reach cms energies $\sim 3.4\ (2.2)$ TeV/nucleon, with similar luminosities. In this contribution we show the physics program that such high-energy DIS machines can provide standalone, comprising precision QCD in $ep$ and $eA$, EW, top and Higgs physics, and BSM searches.
