Getting under the skin of atomic nuclei using #antimatter The AEgIS Collaboration lays the groundwork for a new tool to probe the outer periphery of atomic nuclei. Find out more: https://lnkd.in/dWZYaTE2

So it has begun… the heavy-ion run at the #LHC 💪 This week, a new #HeavyIon run began at the Large Hadron Collider, smashing together lead ions, recreating the extreme conditions of the early #Universe and producing the quark–gluon plasma. Here we see event-displays of lead–lead collisions recorded by the LHC experiments: ATLAS Collaboration, CMS Collaboration, ALICE Collaboration, LHCb Collaboration. For the next two weeks, every minute counts to take lead–lead collision data. This run will conclude with a high-intensity test, which will probe the LHC’s behaviour under conditions closer to those expected at the #HiLumiLHC. Find out more: https://lnkd.in/dUGAThxY

ALPHA measures tiny energy gap in antimatter with improved precision 💫 The ALPHA Collaboration has increased the precision of its measurement of the ground-state hyperfine splitting of antihydrogen by two orders of magnitude. Find out more: https://lnkd.in/dhDX2yJp 

What’s going on at the #LHC? 🤔 While the Large Hadron Collider mostly collides protons, once a year it collides heavy ions – such as lead nuclei – a key ingredient for recreating the extreme conditions of the early #Universe. Hear from Silvia Pisano, Run Coordinator at the ALICE Experiment, about this year’s heavy-ion run at the LHC, and what’s happening after it. The run will conclude with a two-week high-intensity test, which will probe the LHC’s behaviour under conditions closer to those expected at the #HiLumiLHC. #AskAPhysicist #LHCRun3 ALICE Collaboration

It’s a wrap for proton–proton collisions at the #LHC💫 Here we see the event displays of the last proton collisions, recorded on 15 and 16 May by the CERN experiments: ATLAS Collaboration, CMS Collaboration, ALICE Collaboration and LHCb Collaboration. The experiments are now preparing for three weeks of lead-ion collisions, before the official end of #LHCRun3 and the start of the road to #HiLumiLHC, the successor to CERN’s Large Hadron Collider. #FunFact: the next time the experiments will be detecting particles again from proton–proton collisions will be in four years.

The CERN Council decided to update the European Strategy for Particle Physics Today, following more than two years of intense work of the European particle physics community under the auspices of the European Strategy Group, the CERN Council updated the European Strategy for Particle Physics #ESPP, which sets out an ambitious scientific vision for the field. The 2026 Strategy update offers a clear path to maintain European leadership in high-energy physics while attracting global collaboration to CERN, advancing technology and bringing many potential benefits to society. The recommendations address a broad range of topics and goals relating to research in high-energy physics in Europe and beyond. 🔗 Find out more: https://lnkd.in/eHQr-Rmf #FrontlinePhysics
