The CMS Collaboration congratulates individuals who have made significant contributions across the experiment by offering a CMS Award. These annual awards highlight the essential work done in detector operations, software development, data analysis,…

  CMS observes rare collisions that produce pairs of electrons or muons with the highest combined invariant mass ever recorded, extending the search for undiscovered heavy particles. The CMS experiment at CERN has carried out one of its most sen…

The CMS experiment reports the observation of a peaking structure in the Υ(1S)ϕ(1020) channel in proton-proton collisions at 13 TeV. Using the Run 2 proton-proton collision dataset collected at the LHC between 2016 and 2018, the CMS Collaboration ha…
