🤩 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:

Our kind of biscuit tray — but with hexaboards for the future High Granularity Calorimeter (HGCAL), planned for the Hi-Lumi LHC upgrade. The increased granularity of HGCAL will help better distinguish signals from different particles.⚛️.🏆 HGCAL Image of the Month.📸 HGCAL team

All credits to CMS! 📸These event displays are visual representations of particle collisions, reconstructed from signals recorded by CMS. As particles pass through detector, they leave traces, which are processed & transformed into these stunning displays by specialised software.

It's almost time for some new faces to take the stage in our upcoming collab with Ensemble Stars!! Music. Which duo are you excited to see?. Collaboration starts September 4~
