Description
The LHeC provides a comprehensive physics programme with strong implications on that of the HL-LHC. We will present a chapter of the 2020 LHeC Conceptual Design Report update [1], that is firstly the implications of the precise determination of proton PDFs at the LHeC on the measurement of key SM parameters at the HL-LHC: EW mixing angle, W mass and their impact on EW precision measurements. Then we will address the impact of the LHeC PDFs on Higgs measurements at the HL-LHC, and the results for Higgs couplings from a joint $ep+pp$ analysis. We then discuss the impact of LHeC results on high-mass searches. Finally we discuss the impact of $ep$ and $eA$ measurement on the heavy-ion programme at the HL-LHC.
