In the first search of its kind at a particle collider, the CMS experiment looks for partially visible sprays of particles (jets), containing leptons and dark matter using physics-informed machine learning. Can we shed light on dark matter? Ou…

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…
