W boson turns 40
Forty years ago today, physicists at CERN announced to the world that they had discovered the electrically charged carrier of the weak force, one of nature’s four fundamental forces
ATLAS delivers most precise luminosity measurement at the LHC
Precise knowledge of luminosity is crucial for both searches for new phenomena and precision measurements of known Standard Model processes
LHCb brings leptons into line
Simultaneous measurements of rare B-meson decays using the full LHC Run 1 and 2 data samples agree with the predictions of the Standard Model, superseding previous results that had indicated intriguing departures from the 50-year old theory
ATLAS moves into top gear for Run 3
In their first Run 3 results, the ATLAS collaboration measured two Standard Model processes: the production of Z bosons and top-quark pairs
