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.
CMS completes a new DAQ Server room in preparation for Hi-Lumi
The increase in data processing capabilities means that CMS is one step closer to being ready for Run 4.
How to weigh the W boson using hadrons
An interactive version of the event display is found on a separate, full page here.
An all-round boosted chase for supersymmetry
The CMS collaboration expands the search for supersymmetry by exploring a wide variety of final states with boosted particles, in a new analysis called “razor boost”.
