The result opens a new window into the study of the quark–gluon plasma that is believed to have filled the Universe briefly after the Big Bang

For the next 17 days, every minute counts when it comes to taking lead–lead collision data

Fabiola Gianotti, CERN Director-General, was spokesperson of the ATLAS experiment at the Large Hadron Collider from 2009 to 2013 and responsible for announcing the discovery of the Higgs boson, alongside the CMS spokesperson

The ATLAS experiment at the LHC reveals how pairs of top quarks are produced along with other heavy quarks

With its updated analysis methods, the ATLAS collaboration has significantly improved the precision of its measurements of Higgs boson interactions

The results open up a new perspective on the complex world of quantum physics

The ATLAS collaboration has released its first results from searches for new physics phenomena conducted with data from Run 3 of the LHC

CERN’s accelerators show very good availability rates: beams are in place

Restarting the entire accelerator complex after a technical stop is rarely seamless and often comes with unexpected technical challenges

The measurement is the most precise yet made by a single experiment

New ATLAS measurement of lepton flavour universality, a key feature of the Standard Model, in decays of the W boson is more precise than all previous measurements combined

The recently launched Next-Generation Triggers project is set to remarkably increase the efficiency, sensitivity and modelling of CERN experiments
