In a first search of its kind at the LHC, the CMS experiment looks for light beyond-the-standard-model particles with a mass in the GeV range that decay into charged hadrons and muons. It establishes that if they exist, they would be produced…

  The CMS experiment announces several new results for the Lepton-Photon conference and upcoming topical conferences in fall 2025. A major highlight is the high-precision measurement of the integrated luminosity. With an uncertainty of 0.73%, th…

  In a much anticipated result, the CMS experiment presents the legacy combination of Higgs boson studies using the full LHC Run 2 data, recorded between 2016 and 2018 – the result is the most precise and comprehensive measurement of the Higgs b…
