Join scientists live from the underground cavern of the ATLAS experiment tomorrow on social media

On Friday 28 May 2021, the final "wedge" of the first ATLAS New Small Wheel was installed in the detector. This was an important milestone for the Collaboration, in preparation for the wheel’s installation in the ATLAS cavern later this summer

On 13 April 2021, the recipients of this year's ATLAS PhD Grant were celebrated in an online ceremony

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
