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.
-
Hunting exotic Higgs bosons decaying to lightweight scalar particles
In a first search of its kind at the LHC, the CMS experiment looks for light beyond-the-standard-model particles with a mass in the GeV range that decay into charged hadrons and muons.

CMS at Lepton-Photon 2025
The CMS experiment announces several new results for the Lepton-Photon 2025 conference.
-
From pieces to precision: building the Higgs boson’s clearest portrait to date
In a much anticipated result, the CMS experiment presents the legacy combination of Higgs boson studies using the full LHC Run 2 data, recorded between 2016 and 2018 – the result is the most precise and comprehensive measurement of the Higgs boson by CMS to date.

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 How strict are Nature’s conservation laws governing the interactions among elementary particles?
-
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.

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”.
