Tae-Jeong Kim has joined Florencia Canelli as Deputy Spokesperson, working with Anadi Canepa as Spokesperon for the CMS Collaboration for 2026-2028. Now with over 6000 people, CMS remains one of the world’s largest scientific collaborations. The coll…

For the first time at the LHC, W and Z bosons and TeV-scale jets are seen alongside a proton that survived the collision intact, reopening a chapter of forward physics that high pileup had closed. In exploring the strong interaction at the highest co…

  The CMS experiment utilises proton–proton collision data collected between 2016 and 2026 to search for rare decays of the W boson into three charged hadrons. The W boson, which carries the weak nuclear force, was discovered at CERN in 1983 by…
