The result showcases the power of the LHC to push the precision frontier and improve our understanding of nature

ATLAS experiment places some of the tightest limits yet on magnetic monopoles

New result from the ATLAS experiment at CERN reaches the unprecedented precision of 0.09%

The ATLAS and CMS collaborations have joined forces to establish the first evidence of the rare decay of the Higgs boson into a Z boson and a photon

The ATLAS collaboration tested Higgs-boson interactions with the carriers of the weak force, looking for signs of charge-parity symmetry violation

The ATLAS and CMS collaborations have both observed the simultaneous production of four top quarks, a rare phenomenon that could hold the key to physics beyond the Standard Model

An improved ATLAS measurement of the W boson mass is in line with the Standard Model of particle physics

The ATLAS collaboration at CERN welcomes a new management team at its helm. Spokesperson Andreas Hoecker (CERN) will continue to steer the experiment until February 2025

Precise knowledge of luminosity is crucial for both searches for new phenomena and precision measurements of known Standard Model processes

In their first Run 3 results, the ATLAS collaboration measured two Standard Model processes: the production of Z bosons and top-quark pairs

On Friday, 18 November, a test using collisions of lead ions was carried out in the LHC and provided an opportunity for the experiments to validate the new detectors and new data-processing systems ahead of next year’s lead-lead physics run.
