The CMS experiment reports the first observation of a “wake” created by a fast-moving parton in quark-gluon plasma. Wake effect in quark-gluon plasma When the LHC collides heavy nuclei, such as lead, at nearly the speed of light, it creates qu…

  The CMS experiment uses its largest sample of B mesons to date to perform a high-precision test of subtle differences between matter and antimatter. One of the greatest mysteries in physics is why our universe is made almost entirely of matter…

29th of June 2026 saw the end of the LHC Run 3, and the end of the LHC as we know it! The next time CMS records particle collisions, it will be in 2030, provided by the HL-LHC, and from a very different detector to what we have today. CMSers gathered…
