Our CMS physicists at CERN are working on something big: the first prototype slice of HGCAL, the largest silicon-based detector ever built. This is a step in the plan of technical upgrade CMS will undergo starting in 2026.

🤩 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...
