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…

The strong nuclear force is the most mysterious of the four fundamental forces of nature. By studying four-way energy correlations between particles produced by the strong nuclear force, researchers at the CMS experiment have taken another step forwa…
