Description
This largely historical colloquium is devoted to the evolution of experimental particle physics at colliders from the early 80s to the present, and beyond that to what is expected at the HL-LHC. I will cover my own experience from UA2 (1982-1990) to ATLAS (1984-2022) in some detail, from the discovery of the W/Z bosons at the CERN SppbarS to that of the Higgs boson at the LHC. While the discovery of the W and Z bosons was fully expected based on the observation of neutral currents in the bubble chamber Gargamelle in 1974, that of the Higgs boson was expected many years ago at LEP, then at the TeVatron, but nature had decided that its mass was such that it ended up being observed much later at the LHC, in a variety of decay and production modes. I will highlight where we stand today with the measurements of the properties of this wonderfully new and exotic particle, and give a brief glimpse into the future of Higgs physics at the HL-LHC and beyond.
