While the discovery of the Higgs boson in 2012 by the ATLAS and CMS Collaborations remains the LHC's crowning achievement, the ATLAS Collaboration has since produced a wealth of groundbreaking results that continue to reshape particle physics. In this feature article, Andreas Hoecker delves into the remarkable breakthroughs uncovered by ATLAS using Run 2 data.

Julia Gonski explains the long-established use of artificial intelligence and machine learning (AI/ML) in high-energy physics research and explores the exciting potential these technologies hold for the field.

Stefan Guindon, Christian Ohm and Caterina Vernieri describe the major ‘Phase II’ upgrades taking place to prepare the ATLAS detector for the High-Luminosity LHC.

Stars, planets, animals, plants, you and me – everything that can be directly observed in our Universe is ordinary matter. But the Universe didn’t always look this way. This ATLAS feature describes the quark-gluon plasma, a unique state of matter that existed shortly after the Big Bang. The nature and properties of this matter are being revealed at CERN’s ATLAS Experiment.



Twenty-five years on from the discovery of the top quark, ATLAS physicist Richard Hawkings discusses the history of the particle's discovery, its place in the Standard Model and what it has still yet to tell us.

In 2017, the ATLAS and CMS Collaborations announced the detection of a never-before-observed process: vector boson scattering.

When we look around us, at all the things we can touch and see – all of this is visible matter. And yet, this makes up less than 5% of the universe.

Many questions in particle physics are related to the existence of particle mass. The “Higgs mechanism,” which consists of the Higgs field and its corresponding Higgs boson, is said to give mass to elementary particles.

A commentary by ATLAS physicists Paul de Jong and George Redlinger on the history, progress and future of the search for supersymmetry.
