Insight ATLAS - Today and Tomorrow

This talk will present insights into the current status of the ATLAS experiment at CERN, highlight selected results, and discuss future prospects in the context of the High-Luminosity LHC (HL-LHC), expected to begin operation in 2030. Emphasis will be placed on precision measurements of Higgs boson properties and some key electroweak observables, which may offer a window into the mechanism of electroweak symmetry breaking and the structure of the Higgs potential. While the Standard Model continues to describe observed phenomena with remarkable precision, it leaves several fundamental questions unresolved — such as the origin of the matter–antimatter asymmetry, the nature of dark matter, or how neutrinos gain mass. Precision measurements of high-energy proton-proton collisions may provide indirect hints or constraints on new physics that could address these open questions.
