I just had a tour around the DESY labs where parts of the next trackers (ATLAS and CMS) are being constructed. Amazing setups and professionalism 🤩
Every picture has an enormous amount detail behind it. Super nice to see it in real life (thanks to Elisabetta and Doris 🙏).

🤩 In a first-of-its-kind search at the LHC, CMS probed Higgs boson decays to new light particles that give charged hadrons and muons. The results: such decays, if they occur at all, are limited to less than 0.01% of all Higgs boson decays. Read more: cms.cern/news/hunting...

The ULB JUNO group is delighted to share an important milestone for JUNO, the world’s largest underground neutrino detector. After ten years of design and construction, the JUNO experiment started data taking on 26/08/25, with the central detector fully filled with 20K tonnes of liquid scintillator.
