If spotting one #Higgsboson is interesting, what happens when you spot two at the same time? In a new analysis, physicists at the ATLAS Experiment at CERN are looking for Higgs-pairs in the complex soup of particles created by the LHC. Learn more ⤵️ atlas.cern/Updates/Briefi…

The next-generation triggers for CERN detectors 💫

#DidYouKnow that #LHC experiments require high-performance event-selection systems – known as “triggers” – to filter the flow of data to manageable levels? The triggers pick collision events with distinguishing characteristics

40+ years post-discovery, the Z boson remains a cornerstone of particle physics research!

Fresh results from the ATLAS Experiment CERN examine Z boson production alongside heavy-flavour quarks, shedding light on the proton's inner workings. Learn more ⤵️ atlas.cern/Updates/Briefi…

If you want to study key particles of the Universe – be it the #Higgs boson or W/Z bosons – you need to measure and identify electrons and photons. The ATLAS Experiment at CERN has made significant advancements in doing just that.

“Besides his outstanding contributions to particle physics, Peter was a very special person, an immensely inspiring figure for physicists across the world, a man of rare modesty, a great teacher and someone who explained physics in a very simple and yet profound way. (1/2)

Can you guess what this is?
Hint: it has absolutely nothing to do with the sophon in the #3BodyProblem 😉

Here we see part of the future inner silicon tracker (ITk) of the ATLAS Experiment. It will completely replace the experiment’s inner detector in preparation for the

#BeamTime is back at the LHC!

The ATLAS Experiment has recorded its first 13.6 TeV collisions of 2024! This marks the beginning of physics for the third year of Run 3 of CERN's flagship particle accelerator – and the start of an incredible new data harvest for ATLAS physicists.

Happy faces in the ATLAS Experiment Control Room, as shifters ready for high-intensity physics data! 👏

ATLAS provides first measurement of the W-boson width at the LHC! Learn more in our new briefing ⤵️ atlas.cern/Updates/Briefi…

The ATLAS Collaboration has just released its first measurements of W and Z boson production using #LHCRun3 data!

This new result marks a significant addition to our understanding of these force-carrying particles in the 13.6 TeV energy regime. ⤵️ atlas.cern/Updates/Briefi…

The delicate balance of lepton flavours

The @ATLASExperiment recently presented the most precise measurements of lepton flavour universality.

Lepton flavour universality is a key feature of the #StandardModel . This recent measurement was done using decays of the W boson,

In a new result, physicists at the ATLAS Experiment at CERN tested 'lepton flavour universality' - a key feature of the #StandardModel - with record precision.

It's #BeamTime at the LHC! 🎆

Last Friday, the ATLAS Experiment at CERN recorded its first beam-splashes of 2024. Using a single bunch of protons from the LHC, these tests shower the ATLAS experiment with particles, providing vital tests for its sub-detectors.
