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.
CMS at the Initial Stages 2025 conference
At the Initial Stages conference, CMS announces first brand new results based on the recent oxygen-oxygen and neon-neon collision data.
When light turns into weak heavy bosons
Turning the LHC into a photon collider, the CMS experiment observes for the first time how two photons fuse and convert into two W bosons. Stringent limits are set on parameters that would describe possible deviations from the standard model.
CMS at Lepton-Photon 2025
The CMS experiment announces several new results for the Lepton-Photon 2025 conference.
On the hunt for a rule-breaking heavy boson
The CMS Collaboration probes decays of the Z boson which would defy our expectations of lepton behavior
CMS measures WH charge asymmetry — a novel probe of the Higgs–charm interaction
Measuring the charge asymmetry in W boson-associated production for the first time, paves the way for testing the coupling of the Higgs boson to charm and lighter quarks.
