This result is not a sprint, it is a marathon. How the teams behind the measurement of the W-boson mass at the CMS experiment found working on this result, almost a decade in the making. Precision measurements like that of the mass of the W boson…

The CMS Experiment welcomed more than 300 collaborators during the CMS Upgrade Week from September 16 to 20, 2024. The week showcased the immense amount of work underway to transform the CMS detector ready for the LHC High Luminosity era, also known…

The CMS collaboration welcomes its tenth management team: the new spokesperson, Gautier Hamel de Monchenault, and the two deputies, Hafeez Hoorani and Anadi Canepa. They will be representing CMS over the next two years (2024-2026). With more than…

CMS physicist Dr Jennifer Ngadiuba wins the IUPAP C11 Early Career Award 2024. This prestigious award honours two early career scientists for their excellence in the field of Particles and Fields during the biannual ICHEP conference. Congratulations…

Starting in 2029, the High-Luminosity LHC (HL-LHC) will provide much higher collision intensities to the ATLAS and CMS experiments, with up to 200 concurrent collisions (or pileup) per bunch crossing expected. This will create very complicated…

Since the year 2000, the CMS Collaboration has recognised industry partners who've played a crucial role in building the experiment. The CMS Gold Award acknowledges companies that consistently deliver high-quality components, meeting deadlines and…

The CMS Collaboration is thrilled to announce that laureates of the 2023 CMS PhD Thesis Award are Jona Motta, Christopher Edward Brown, and Spandan Mondal. This award recognizes exceptional doctoral research within the collaboration that pushes the…

It's time to shine a light on the 2023 CMS award winners! Each year, the CMS Award committee recognises outstanding contributions from members of the CMS Collaboration, honouring their dedication to the performance of CMS sub-detectors and,…

In physics research, results are frequently represented in complex diagrams, and colour is an essential tool to help the reader extract key information.  Making sure our colour schemes are friendly to people with colour-vision deficiency (CVD…

Peter Higgs was one of the pioneers who brought the electroweak theory and the Standard Model of particle physics into being in the 1960s. He posited a new field and particle that would provide a mechanism for how elementary particles gain mass. The…

The CMS experiment at CERN is proud to announce the first release of 13 TeV proton-proton collision data collected in 2016. Over 70 TB of 13 TeV collision data and 830 TB of corresponding simulations are now accessible to the global scientific…

  The time has come to wrap up the year! Ready? Let’s do it! Not only did CMS celebrate the restart of LHC Run 3 in April at the record energy of 13.6 TeV, but this year also saw the long-awaited Heavy-Ion run. It marked the first Heavy-Ion run…
