In a recent measurement, the CMS experiment confirms a slight but persistent disagreement between the simulated and the observed rates of events in which a top quark pair is produced accompanied by a W boson.
The CMS experiment has conducted a comprehensive study of the rates of production of top quark pairs created along with a photon, both inclusively and as a function of several kinematic variables.
The CMS experiment studies the Higgs boson as a potential window into dark matter, and sets constraints on this mechanism, which gives rise to isotropic sprays of low-energy particles.
The ratios of the B meson production fractions have been measured for the first time in the CMS experiment.
The CMS Collaboration announces 50 new results for Moriond 2025.
CMS discovers associated production of a Z boson and an ϒ meson.
New BRIL subsystems illuminate CMS’s path through Run 3
The TBPS Rings are in production, offering an innovative design to incline sensors toward the LHC beam and maximise coverage. They are the first support structures in production for the new Tracker!
The first of the improved Resistive Plate Chambers for Hi-Lumi CMS were installed in record time during the LHC winter break.
