ATLAS sets record limits on Higgs boson’s self-interaction
The result is based on over 300 inverse femtobarns of proton–proton collision data, which is equivalent to 30 000 trillion collisions
-
ATLAS acts as a cosmic-ray laboratory
The ATLAS Collaboration reports its first measurement of proton–oxygen collisions at the LHC, which recreate cosmic-ray interactions with Earth’s atmosphere

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
-
ATLAS closes in on rare Higgs decays
The ATLAS collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon.
