The ATLAS search achieves the world’s best constraints on the size of the Higgs boson’s self-coupling, creating a portal of better understanding into the fundamental Higgs mechanism

In new results, ATLAS physicists describe novel techniques used to accurately align the muon spectrometer

The 2020 ATLAS Outstanding Achievement Awards and Thesis Awards were presented on 11 February

The ATLAS collaboration welcomes new management this month, with Andreas Hoecker (CERN) taking the lead as Spokesperson for the experiment

Over the past 10 years, the LHC has found more than 50 new particles called hadrons

The ATLAS experiment at CERN finds evidence of a rare Higgs boson Dalitz decay to two leptons and a photon

The new collection of 200 additional software packages make most ATLAS software open and reinforces ATLAS’s commitment to open science

The result surpasses previous best mass limits achieved with CERN’s predecessor collider to the LHC

The ATLAS Inner Detector can measure the position of charged particles that pass through it to better than a 100th of a millimetre! To reach that precision, the detector must be aligned to equal or better accuracy

The ATLAS experiment reports the observation of photon collisions producing weak-force carriers and provides further insights into their interactions

The ATLAS and CMS experiments at CERN have announced new results which show that the Higgs boson decays into two muons

A new ATLAS measurement of a key feature of the Standard Model known as lepton flavour universality suggests that a previous discrepancy measured by the LEP collider in W boson decays may be due to a fluctuation
