CMS develops and deploys a new machine-learning technique based on neural networks that is able to spot existing and developing anomalies in the functioning of the detector. In the quest to uncover the fundamental particles and forces of nature, one…

On Friday, October 4th, 2024, the CMS Collaboration organised an in-person event at Point 5 for the residents of the Pays de Gex, France, where the CMS detector is located. For the first time after COVID-19, the local community was invited to visit…

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…

  Going back to the origins, in a latest result, the CMS experiment rediscovers the Higgs boson and measures its rate of production in the "golden channel", now at the unprecedented centre-of-mass energy of 13.6 TeV. The discovery of the Higgs…

  In a recent result, the CMS experiment measures the production of charmed D0 mesons in collisions of a photon with a heavy lead nucleus for the first time. Atomic nuclei are made up of protons and neutrons, which in turn are made up of more…

The CMS Collaboration has announced 14 new results for summer topical conferences – Higgs Hunting 2024, Hard Probes 2024, and TOP 2024. In HIG-22-013, we present a search for a heavy scalar or pseudoscalar boson decaying to a top quark-antiquark…

In an extraordinary feat of precision physics, CMS measures the mass of the W boson, and finds it to be in good agreement with the prediction by the Standard Model of particle physics. In the most precise measurement of its kind ever obtained at the…

  A primary goal of the Large Hadron Collider (LHC) is to hunt for evidence of beyond the Standard Model (BSM) dynamics through deviations from the Standard Model (SM) predictions. If the mass of BSM particles exceeds the energy accessible in…

  With the discovery of the Higgs boson in 2012, an important piece in our puzzle to understand the Universe was found. However, there are still many open questions: why is the Higgs boson so light? What is dark matter? How does gravity work at…

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…

  The Higgs boson is a fascinating elementary particle, and its discovery twelve years ago cemented the standard model (SM) of particle physics as the most accurate description of nature at and below the electroweak energy scale. However, many…

  At the LHC, lead ions are smashed together at extremely high speeds to create a unique state of matter called the quark gluon plasma. Normally, quarks and gluons, such as those that make up lead ions, are confined within protons and neutrons…
