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…
CMS presents the most precise measurement of WWZ production to date by combining Run 2 data with more recent Run 3 data.
The electroweak interaction provides a unified description of the electromagnetic and weak forces, but this symmetry is broken…
Going back to the origins, in a latest result, the CMS experiment rediscovers the Higgs boson and measures its rate of production in the "golden channel", now at the unprecedented centre-of-mass energy of 13.6 TeV.
The discovery of the Higgs…
In a recent result, the CMS experiment measures the production of charmed D0 mesons in collisions of a photon with a heavy lead nucleus for the first time.
Atomic nuclei are made up of protons and neutrons, which in turn are made up of more…
Our current understanding of the nature of elementary particles and their interactions is encapsulated in what is known as the Standard Model (SM) of particle physics. Particles and interactions introduced in the SM have been measured with…
In 2012, the discovery of the Higgs boson marked a milestone in particle physics. It validated the standard model (SM) and unlocked new avenues of exploration. In 2022, the Higgs boson turned ten and the CMS experiment now presents a new…
