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

Using data from Run 2 of the LHC, the experiment has combined a comprehensive set of searches for di-Higgs production, a phenomenon that could provide physicists with clues to the stability of the Universe

The collaboration has found evidence of CP violation in decays of baryons and in decays of beauty hadrons into charmonium particles

The finding also represents the first evidence of the heaviest antimatter hypernucleus yet at the LHC

Isoprene emitted by tropical forests may provide a globally important source of aerosol particles that influence clouds, according to a new study by the CLOUD collaboration at CERN

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

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

Using data from the first heavy-ion run of LHC Run 3 in 2023, the experiment presents the first-ever measurement of D0 meson production in photon-lead collisions
