In Run 3, CMS expanded its trigger program to enhance capturing long-lived particles that decay far away from the point of collision – broadening the search for physics beyond the Standard Model. Imagine a high-security vault. Most intruders t…

For the first time ever, the CMS experiment has designed a dedicated analysis using parametrised machine learning to look for new dark particles that don’t socialize with Standard Model fermions, one of them being a favourite candidate in the search…

  The CMS Collaboration reports the first measurements of the production of same-sign WW and WZ boson pairs in association with two jets at 13.6 TeV, using data collected during 2022–2024. One of the most powerful probes of the Higgs mechanism a…
