The CMS Collaboration announces more than 40 new results for Moriond 2025. In Higgs physics, following a comprehensive research program aimed at characterizing the Higgs boson by measuring its properties and interactions across various decay a…

  The CMS experiment conducts the first search for dark matter particles produced in association with an energetic narrow jet—the pencil jet. Dark matter remains one of physics’ greatest mysteries. Despite making up about 27% of the universe’s e…

  In a recent measurement, the CMS experiment confirms a slight but persistent disagreement between the simulated and the observed rates of events in which a top quark pair is produced accompanied by a W boson. One of the goals of the CMS experi…
