Upon close inspection, the tetraquark family members are consistent with tightly bound diquark pairs The CMS Collaboration has identified three extremely rare same-flavor teraquark states and determined, based on their spin-parity configuration,…

  The CMS experiment utilises cutting-edge machine learning techniques to search for microscopic, quantum black holes and other exotic objects that evaporate in an instant. Black holes are amongst the most fascinating objects in the universe.…

  The CMS experiment announces new results for the Higgs 2025 conference. For the Higgs 2025 conference, CMS publishes a number of new results. The LHC Run 2 Legacy on Higgs boson pair production is obtained in an ATLAS+CMS combination (HIG-25-…

  Using data collected from 2016 to 2023 and cutting-edge machine learning, CMS observes for the first time the creation of a top quark together with a W and a Z boson – a process so rare it occurs only once in a trillion proton-proton…

  In the first search of its kind at a particle collider, the CMS experiment looks for partially visible sprays of particles (jets), containing leptons and dark matter using physics-informed machine learning. Can we shed light on dark matter?…

Five years after the first evidence that heavy metal hits the top quark, CMS now observes the clash of two titans with higher precision at unprecedented energy. Using lead-lead collision data acquired in 2023 at the highest energy ever achieved by…

  CMS scientists are on the hunt for a new, heavy particle that decays into a pair of Higgs bosons. Using the final state with two bottom quarks and two tau leptons, the search sets the most stringent limits to date in the mass range 1.4–4.5…

  The CMS experiment is utilising a novel technique called L1 Scouting, which allows it to record data from all collisions, without any selection, but in a reduced format. A first pioneer physics result using this data showcases the immense…

  CMS observes collective motion of particles in light-ion collisions, providing robust evidence of how initial nuclear geometry maps to final-state flow. For the first time, the CMS experiment has measured how particles flow in collisions of…

  The CMS experiment has analyzed the first-ever neon-neon collisions, looking for signs of quark-gluon plasma. By comparing these results with data from oxygen-oxygen, xenon-xenon, and lead-lead collisions, physicists find an interesting…

  CMS scientists study the first-ever oxygen-oxygen collisions at the LHC, and observe signs of quarks and gluons losing energy when they travel through quark-gluon plasma – a state that existed just after the Big Bang. When heavy ions such as…

  At the Initial Stages conference, CMS announces first brand new results based on the recent oxygen-oxygen and neon-neon collision data. The new data offers unique opportunities to study the collective phenomena and initial-state effects in…
