Abstract: The discovery of the Higgs Boson by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) in Geneva, Switzerland, was one of the most important and exciting moments in particle physics. The field of particle physics has transitioned to a new phase that presents us with the opportunity to gain a deeper understanding of the fundamental nature of matter and our universe. I will discuss some of these implications, which inform the efforts to figure out the roadmap of particle physics in the coming decades. Starting around 2026, the High-Luminosity LHC (HL-LHC) will deliver proton-proton collisions at a center-of-mass energy of 14 TeV. I will summarize the studies from a comprehensive campaign mounted in 2018, to understand the physics reach of the experiments at the HL-LHC and a possible higher energy LHC (HE-LHC) at 27 TeV.
