A needle in the pileup: CMS revives diffractive physics with tagged protons
For the first time at the LHC, W and Z bosons and TeV-scale jets are seen alongside a proton that survived the collision intact, reopening a chapter of forward physics that high pileup had closed.

The W boson’s simplest decay into hadrons
The CMS experiment utilises proton–proton collision data collected between 2016 and 2026 to search for rare decays of the W boson into three charged hadrons.

Four gets you more: understanding the strong force with four-way energy correlations
The strong nuclear force is the most mysterious of the four fundamental forces of nature.

In search of unknown forces: Do W and Z boson pairs reveal new interactions?
CMS sets the world’s most stringent constraints on anomalous interactions between the bosons that carry the electroweak force.

Lepton–lepton scattering in proton–proton collisions
The CMS experiment uses data collected between 2016 and 2026 to observe, for the first time, leptons (electrons and muons) emitted from protons scattering off one another.

Looking for new physics at the multiboson frontier
The CMS experiment presents a novel search for new physics by studying collisions that produce three W or Z bosons.

The curious case of quarkonia inside jets
The CMS experiment presents a first study of the ϒ mesons (bound states of a bottom quark and antiquark) produced within jets.

CMS observes rare Z boson pair production
For the first time, the CMS experiment has observed the rare electroweak production of two Z bosons in association with two jets.

First measurements of vector boson scattering at 13.6 TeV
The CMS Collaboration reports the first measurements of the production of same-sign WW and WZ boson pairs in association with two jets at 13.6 TeV, using data collected during 2022–2024. One of the most powerful probes of the Higgs mechanism and the electroweak force is a rare process known as vector boson scattering (VBS).

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.
