Earlier this week, a team of scientists from the BASE experiment #AtCERN succeeded in transporting antiprotons in a truck across the Laboratory’s main site.
Christian Smorra explains how the BASE-STEP portable antiproton trap captures and stores antiprotons.
CMS strengthens the case for toponium
A new independent measurement by the @cmsexperiment.bsky.social at the #LHC is consistent with the existence of the most massive composite particle ever observed, the momentary union of a top quark and its antiquark.

Today, she shares insights into the future plans for the world’s largest machine as we prepare to transform the LHC into the #HiLumiLHC, a groundbreaking accelerator that will usher in a new era for high-energy physics.
The future of physics 💫
Last week, Chiara, an accelerator physicist, took us to the CERN Control Centre (CCC) to explain the restart process for the Large Hadron Collider (#LHC).
The projects will support a wide variety of activities, including advancing accelerator technologies and creating access networks for medical and aerospace research.

#FunFact: The first event displays in particle physics were direct images of traces left by particles when they interacted with gases or liquids. Today, experiment teams use software to convert data into graphical objects, which are then rendered in a specialised application.
Sailing the high energies ⚡
These are the first high-energy collisions recorded by the #LHC experiments in 2026.
Representing particle collisions at an energy of 13.6 TeV, these event displays mark the beginning of the experiments’ data-taking season and the final #LHCRun3.
