The ATLAS Collaboration reports its first measurement of proton–oxygen collisions at the LHC, which recreate cosmic-ray interactions with Earth’s atmosphere
Using machine-learning techniques, the ATLAS Collaboration has searched deep for signs of particles that could help answer some of the greatest mysteries of physics
ATLAS 2025 Thesis Awards spotlight the “soul” of the Collaboration
On 19 February 2026, the ATLAS Collaboration gathered for the 2025 Thesis Awards – an annual celebration of the vital role of PhD students within the experiment
Shape-shifting collisions probe secrets of early Universe
The first high-energy collisions between light nuclei at the Large Hadron Collider confirm the unusual “bowling-pin” shape of neon nuclei and offer up a new tool to study the extreme state of matter produced in the aftermath of the Big Bang
Elusive romance of top-quark pairs observed at the LHC
The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top quarks that suggests that these heaviest of all elementary particles form a fleeting union
Accelerator Report: LHC protons outpacing the Easter tradition
The LHC has restarted and both beams have been circulating in the machine since 8 April, meaning that the start of the LHC beam commissioning during Easter is apparently not a constant of nature
The LHC experiment collaborations at CERN receive Breakthrough Prize
The Breakthrough Prize in Fundamental Physics was awarded to the ALICE, ATLAS, CMS and LHCb collaborations during a ceremony held in Los Angeles on 5 April
