The detection of longitudinally polarised W boson production at the Large Hadron Collider is an important step towards understanding how the primordial electroweak symmetry broke, giving rise to the masses of elementary particles

Spokesperson Stéphane Willocq and Deputy Spokespersons Anna Sfyrla and Guillaume Unal will lead the collaboration for the next two years

Every year, these awards celebrate the outstanding achievements made by PhD students working with the collaboration

ATLAS reports the first observation of a Z boson accompanied by two other carriers of the weak force

New ATLAS measurement of the lifetime of the electrically neutral beauty meson is the most precise to date

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

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

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

By combining multiple Higgs boson pair studies, physicists are closer to finding out how the particle interacts with itself, providing clues to the stability of the Universe

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
