The experiments at the Large Hadron Collider (LHC) continue to confirm the Standard Model (SM) of particle physics with impressive precision, and no conclusive evidence for new physics at the TeV scale has yet been observed. In this context, precision measurements of electroweak observables provide a powerful and complementary approach to exploring physics beyond the SM.
The LHC experiments have delivered a broad and highly precise program of electroweak measurements, probing the internal consistency of the SM through fundamental quantities such as the W- and Z-boson masses, the effective weak mixing angle, and related electroweak parameters. More than forty years after their discovery, the W and Z bosons remain key laboratories for testing the SM, where even small deviations from predicted relations could point to new phenomena.
This talk will review recent high-impact ATLAS results in electroweak precision physics, highlighting both experimental and theoretical challenges and their relevance in the ongoing LHC physics program. Prospects for the High-Luminosity LHC, as well as the role of future collider projects, will also be discussed.
