Five years after the first evidence that heavy metal hits the top quark, CMS now observes the clash of two titans with higher precision at unprecedented energy. Using lead-lead collision data acquired in 2023 at the highest energy ever achieved by t…

The CMS Collaboration is proud to announce the recipients of the 2024 Industry and Partner Awards, which recognise the vital contributions of our partners in advancing the experiment's capabilities. This year, we honour two collaborators for their ex…

  CMS scientists are on the hunt for a new, heavy particle that decays into a pair of Higgs bosons. Using the final state with two bottom quarks and two tau leptons, the search sets the most stringent limits to date in the mass range 1.4–4.5 TeV…
