CMS breaks new ground by reconstructing challenging photon signatures using machine learning, opening new paths in the search for physics beyond the standard model. What if a new exotic particle from a non-standard Higgs boson decay escaped detectio…

  Remember the media buzz when we finally pinned down the Higgs boson in 2012? Turns out it might have a shadowy cousin – the dark Higgs – and CMS is chasing it down. CMS scoured its entire Run 2 data set,138 fb–1 of proton-proton collisions at…

  For the first time, the CMS experiment measures the production of single top quarks in a mode called the “t-channel” at 5.02 TeV, reporting results aligned with the standard model expectations. In the quest to probe the fundamental laws of nat…
